In the third area, water covered half of the kettles. Upon entering the first kettle the Main Six encountered the Octoseeker after finding the Hero Slosher, which was a bucket that could be used to slosh ink all over enemies. The Octoseeker was a giant square vehicle with a large ink stamp on the bottom side, held up by four propellers. After taking on this kettle, they were introduced to bounce pads in the next one. Everybody had fun using the bounce pads to jump higher and avoid attacks. In the next kettle, they found the Hero Splatling. This was an ink gun that would charge up and then rapid fire like a machine gun. They also met the Octocommander, which was similar to the Octosniper, except it would shoot rapid fire. They also came across giant robots that flowed showers of ink nonstop.
"Those are flooders. You can't destroy those, similar to how squee-gs cannot be destroyed.", Agent 3 said.
Some of the kettles did not have very many pathways, or not as many visible pathways. Sometimes, they had to use their ink to find the path. Some of the sunken scrolls they had found in the previous area talked about how Inkopolis was saved from destruction by an octoling, who Agent 8 said was herself. At the boss' lair, they saw an ink filled bubble stuck to the rear wall, but their path was blocked by a mechanical fish with sharp teeth. The fish would swim under the platform and then pop its teeth up around the Main Six. They shot and broke the teeth and got out of the fish's mouth. When the fish closed its mouth and popped above the platform, they threw a splat bomb into the mouth to knock out the fish. Then they shot the tentacle until it burst. They repeated this two more times with the teeth getting made of a metal that was harder to break. One of the gold teeth from the third strike hit the bubble and tore it open. Agent 4 splattered to the floor of the room and then got up before leaving after the zapfish was recovered.
"How's your healing coming along?", Rainbow asked Callie.
"My leg is back to normal, still waiting on my arm.", Callie replied.
The group continued to the fourth area of the canyon, knowing that they would rescue Captain Cuttlefish next. However, they also received another radio transmission. It was so broken up due to static that they could not make it out.
"A--nt d--- - n-e- r--c-e. C-- a-y--e --ar -e?"
"Three, what did you make of that", Callie asked Agent 3.
"I couldn't tell what was being said. Eight and Four are just as confused.", Agent 3 replied.
"I couldn't tell what it was supposed to say either. There was too much static and interference.", Clauds replied sadly.
Nevertheless, they kept going.
