The first thing that Bentley did, after the gang heard what Grizz was up to and what happened to the first Cooper Cane ever to be constructed, was have Murray head out to an area of the village that they were in and set up some training exercises that would help Bob get back in shape, or at least to the point where he'd be able to climb and assist them in recovering the missing components they needed for the time machine. Murray promptly declared that he 'knew what it took to be a champion' and that he was going to put Bob through the training of his life so they could get him back in shape, before heading out to the area that he needed to set up the training course in, allowing the others to relax as best they could and keep tabs on what Grizz was up to. Elizabeth and Daniel seemed to be having fun, despite the fact that they could really only play in the snow while there weren't any guards around, but at the same time they still knew that the situation was dangerous and came back to their safe house if they started to stray too far from Carmelita's sight, though the first time that happened she went out and pulled them back herself. For the most part there wasn't much the gang could do, not until Murray was finished setting up his course and Bob was whipped back into shape, so they made sure to keep themselves as active as possible, and that meant trying to figure out what sort of operation Le Paradox had Grizz running at the moment, because that was something they still didn't truly understand... even though Derpy, Gilda, and Diz thought it was just a way to get Bob in a position so he could be captured.
While all this was going on Sly noticed that Clockwerk spent most of his time outside the safe house, thanks to the fact that his metallic body seemed to have an impressive resistance to the cold air that was around them, though he knew that the owl was looking for something, and it was only a matter of time until they found out what that something was... and in due time Murray called Bob out to the training area, where the prehistoric raccoon grabbed a large bone, to use as a club for now, and headed off to the area that Murray was in.
"Alright, listen up... Playtime is over!" Murray declared, as he was standing on a pillar and was staring down at the entrance that Bob walked through, where he noticed that the Cooper Ancestor was looking at what he had assembled for him, before he was the focus of Bob's attention, "Your job is to get back in shape, and my job is to make sure that you do just that! To do that, The Murray is taking your training to the next level! Look around the area, we'll be using your standard training exercises: Slippery Slope, Penguin Popper, Sumo Slap, Duck and Cover, Super Sling, and Whack-a-Chump."
Bob looked at the six signs that Murray must have created before his arrival, along with naming each and every one of them, before he turned back towards his new friend and tilted his head in confusion, to which he spoke in his native tongue for a few moments, in the sense that he was asking a question.
"Okay, maybe they aren't your standard exercises, but they're Murray approved." Murray replied, as he had known, from the moment he got to this area, that Bob had no actual standard training exercises in this area, meaning that he usually did whatever he wanted to stay in shape, hence the creation of six special challenges that would get the job done in no time, "So, if you're ready, let's get started!"
The first challenge that Bob went for was Slippery Slope, where Murray explained that, due to some advanced training techniques, he had the balance of a mountain goat, a secret that he was going to pass onto Bob, though it was really him standing in the middle of a floating block of ice, holding a log above his head with a pterodactyl egg in the center of it, and the only requirement was that the egg stayed in one piece. At first Bob assumed that the challenge was going to be easy, until Murray revealed that he had some penguins that were willing to help with their training, feral ones that seemed to know better, and that they would be jumping onto the ice to disturb the balance, forcing Bob to adapt so he could keep the egg in one piece. Bob, who had no natural balance to begin with, found that the challenge was hard from the very beginning, but despite that fact he guessed that this would help his regain his former abilities and went along with it, even though he had the urge to drop the log and the egg, pick up his club, and smash several of the penguins while he stayed in a single spot, all because he found the little critters to be absolutely annoying. He wasn't sure how long he had to remain in this state, balancing an egg that he somehow managed to get to stay on the log without it falling off and hitting the ice that he was standing on, but eventually Murray called him off the ice and handed him a item... something that he called a golden metal, which he created for this event and said that it showed that he had good practice with the technique that he had put him through.
From there he moved to Penguin Popper, which was basically just Bob standing under the ledge that some penguins would be walking on, hiding him from their sight while blocking his sight of them, and that this was a test of his reaction time, as he was supposed to hit an opponent when they were right in front of him. This one Bob liked, as it allowed him to take out some of his frustrations on the penguins that had tormented him during the first challenge, to which he gladly readied his club and whacked the penguins as they jumped off the space above them, sending them flying into the distance, even though he knew that they'd come back for another round. Murray made a comment about how tough the penguins were, as Bob's weakest hits still packed enough force to send them flying and yet they returned to them without any marks that they had been hit in the first place, which just confirmed that everything was tougher back in this time period, something that Bentley had noticed and was happy to have confirmation on. Despite his eagerness to hit the penguins, however, Bob did miss two of them on accident, which Murray assured him was okay, and one of them even hit one of the small pterodactyls that were flying through the area, something that they ignored in favor of continuing their training... and, after hitting a number of penguins, how many Bob had no idea since he couldn't count, Murray declared that he was victorious and handed him a second prize, which he added to the pile and moved to the third challenge.
When he arrived at Super Sling, as that was the challenge that was close to Penguin Popper, Murray explained that he needed to develop his accuracy, which was something else that Bob had no idea what Murray was talking about, but he listened as the hippo explained what he was talking about. According to Murray, he could hit the 'bullseye' while standing on his head, but Bob, on the other hand, just had to strap some penguins down into a strange looking device, a 'sling' as Murray called it, and launch the penguin at the stone targets that the pterodactyls were carrying, once more making Bob wonder how Murray had convinced the savage animals to listen to him. Fortunately Bob smiled when he stared at the penguins that were near the sling and loaded one into position, as he was having fun getting payback on these critters, for both the training he was enduring right now and his own problems from before Grizz showed up, and launched the first one into the target when a pterodactyl came close to where he was standing, shattering the stone with the penguin's hard head and causing him to load another one immediately. While he really had no idea what this was supposed to do for him, considering that there were things that Murray said and he didn't understand the words he was speaking, Bob did have fun messing with the penguins and knew that from this day forward they might fear him more than they did in the past, meaning that he'd have a better future once Grizz was taken care of... and despite his lack of concentration near the end, as he missed a few targets in the process, Murray eventually told him to stop and rewarded him with the third prize.
The fourth challenge, Whack-a-Chump, was designed to teach Bob precision, another word he didn't understand at all, but Murray explained that he needed to know when to attack and when to back off, while also describing it as when to grab or back off from a food item. For Bob, however, the challenge was to use his club and smash the penguins that popped out of the holes in the turtle shaped stone that was nearby, while at the same time avoiding the 'fake' birds that would end up costing him points, though that only served to confuse Bob as the challenge started. In his confusion he swung his club and hit some real birds upside their heads, while at the same time shattering some stone birds that didn't move at all, so much so that he actually ended up failing the challenge in 'record time', only for him to exclaim and speak in his tongue about not knowing what a 'fake' bird looked like. Murray was willing to lend an ear and showed him what he meant by 'fake', giving Bob the change to see that the birds he wasn't supposed to hit were definitely made out of stone and that he should be hitting them at all, least the numerous collisions snap his club in half, before he returned to the challenge and swung his club at the real birds. The second time around it was much better for him, as he was able to figure out which targets he was supposed to be hitting and which ones that he needed to ignore, causing Murray to smile as he continued to smack the penguins that were the targets, and in time he was happy to reward Bob with the next prize, encouraging him to do that well in his next challenge.
Sumo Slap, the fifth challenge, was interesting to Bob, as he had no idea that there were penguins of his size, ones that could actually understand him and Murray, and one of them stood in front of him, to do battle in the art of pushing each other towards the side of the ring that they came from, where Murray claimed that he needed to find his inner strength and push his foe back. Bob had to admit that his desire to punish the penguins really didn't help him against his newest foe, mostly because of his sheer size and the fact that their strength was just about equal, but that didn't stop him from trying his hardest to push the penguin backwards like Murray wanted. For the first few attempts Bob found that the penguin had more practice than he did, as his foe was able to push him backwards with his force and engaged in a series of slaps with Bob, but they all ended in him being pushed out of the ring and forced him onto his back, though the more interesting part about this challenge was the fact that the penguin offered him a flipper and pulled him back onto his feet, so they two of them could go at it again, bringing a smile back to Bob's face. It took some time and effort, as well as a decent amount of concentration, but eventually Bob started to find his pacing and managed to turn the tables on his foe at one point, who was both shocked and happy at the same time... and that time around, when he was awarded the metal for winning the challenge, Bob slipped it over the head of the penguin and they both smiled.
Murray, who had been watching the two the entire time they had been sparring, couldn't help but smile as well, as it appeared that Bob might have made a friend, or at least a sparring partner to keep himself in shape, in the penguin, and that was good news for Bob when Grizz had been taken care of.
The final challenge was duck and cover, where Murray would be using his own strength to hurl penguins at Bob while he stood in the same position, though what Bob needed to do was to watch where the penguins were coming from and move his body accordingly. That meant that if they came towards his head he needed to drop to the ground, if they were coming towards his left arm he needed to pull to the right, if one came at his right arm he needed to pull to the left, and, as a real challenge, if one was thrown at his feet he needed to jump into the air and avoid it. Of all the challenges this was, in Bob's mind, by far the easiest of them all, as he was able to dodge the penguins like they were nothing and that pleased Murray, making him throw faster and he even asked if the larger penguin wanted to join in, giving Bob a little bit of a challenge when they threw two penguins and forced him to dodge both of them in rapid succession. Despite that Bob found that victory was eventually his, much to his new friend's joy as he clapped his flippers together, and he gladly accepted the metal that was awarded to him, as well as a few hours of rest, because he had been working hard and deserved some time off before they resumed his training... and Murray made sure that he got something to eat so he didn't work himself to exhaustion.
When Bob was finished recovering from the first stage of his training Murray kicked it into high gear, using a random order generator that Bentley created for the names of his challenges and used it to determine the order that Bob had to tackle the challenges in, meaning it would be an entirely different order than before. The large penguin stuck around and helped them out, doing what he had been doing the entire time they had been there and either fought Bob in the ring, threw more penguins at him, or even helped him do some advanced training exercises that came from the future, all of which was designed to get him back into shape. From that point forward Bob lost track of how long they were in the area that they were training in, stopping only to make sure that he was hydrated and had something to eat every now and then, but he knew, from Murray's words, that they were making progress and he eventually found that he was able to do the future exercises rather easily from what Murray called 'repetition'. His new penguin friend was more than happy to cheer him on and spar with him, as it also made him stronger as a result, and eventually part of the training involved Bob making sure that his new friend could do the same exercises that he had been doing, causing Murray to nod his head in approval as the two of them continued training.
Eventually, however, the training came to a stop when Bob was able to climb the pillar that Murray was standing on, causing him to cheer in happiness for Bob's success, though at the same time Bob and his new friend nodded to each other as they went their separate ways, as they would be back to do this again once Grizz was finished.
Now that Bob was ready to assist the gang, and was able to climb up walls once more, he and Murray left the training area and headed over to the spot where Sly had spotted one of Bentley's missing components, though since there were a number of dodo birds patrolling the area the two of them went to town on them. Murray knew that, despite his own skill at climbing walls and what not, he couldn't actually climb the wall that they needed to get around, so he mostly focused on beating up the guards so that Bob could keep the energy that he had left for the climb, but that didn't stop the prehistoric raccoon from hitting the guards anyway. Once the dodo birds were taken care of Bob approached the icy wall and dug into it with his claws, since that was what they were designed for, while allowing his tail to curl around the handle of his club so he could carry it with him, before Murray watched as he ascended the wall that was in front of him and made his way towards the device that Bentley needed him to recover. Bob's fists also came into play, as there were some bones sticking out of the icy wall and if he pounded the ice he could shatter the brittle bones without damaging the structure he was climbing on, allowing him to progress without really wasting too much time on the obstacles that were right in front of him, while also giving him the ability to focus on his objective.
When Bob finished climbing and reached the area that he was supposed to be navigating himself through, however, he had to pause as he marveled at the binocucom that he had been given, an interesting toy that allowed him to see more than his eyes allowed him and gave him the ability to communicate with Bentley, who couldn't explain how the toy worked since he needed him to get the 'sprocket' back.
Bob immediately climbed up the wall that was in front of him and made sure to jump over the gaps that were in his way, as well as breaking the brittle bones in the wall sections as well, before coming to an area that he could walk though, giving him the change to smash some small pink colored scorpions with his club before he found the way he was supposed to move forward. The next wall segment had some modern challenges he needed to avoid, such as large falling eggs and spikes that erupted from a special designed contraption that Bentley said he'd explain later, but even if Bob was still getting the hang of things again he discovered that these presented him with no real challenge, not after everything that Murray put him through earlier. He even had to loose his grip and slide down the side of the wall at one point, which he considered fun, before jumping over to a new part of his path and climbed up to the nest that the part he had been sent to find had been dropped into, though it was rather easy for him to spot since it was so different from the eggs that were around it. When he moved to collect the part, however, both it and he were grabbed by a pterodactyl, though Bob was forced to let go and watched as the part was taken even higher than before, to which he growled and continued climbing through the new part of the nest that he was in... and the only thing he had to be really careful about was making sure that he didn't wake any of the baby pterodactyls up from their naps, otherwise he was sure that the mama would do something to the device Bentley was after.
This time around, when he found where the device was located, he carefully retrieved it without making any noise and then made his way back down to where the others were waiting for him, as he was sure that Bentley would be happy to have this back in their possession.
When Bob returned to the village he found something interesting, Murray was running around squeezing the five penguins that had apparently swallowed the parts of the other device that Bentley needed, or at least that was what he was told when he arrived on the scene. It was easy to keep them contained to a single area, as it appeared that Diz was using his 'power', another term that Bob was unfamiliar with, to keep the five targets contained in a single area so Murray could get what he came for, forcing the penguins to cough up the parts that they had swallowed. Between the pair and Bob's missions it was clear that Bentley would have the pieces he needed to fix whatever it was that was broken and then, like he promised Bob earlier, they would figure out what they were going to do about Grizz and finally take him out.
