The Doctor and Derpy were awoken by the sound of rattling bones. The Doctor got up and holding the pickaxe, ready to strike, he broke one of the blocks above them. When nothing happened he dug a stair case and helped Derpy out of the hole. As they looked around they saw monsters running about surrounded by blocky fire. One keeled over and others followed, leaving items where they had disappeared. The doctor ran over and gathered the items before returning to Derpy who had re-covered their hole.
The Doctor was about to say something but froze. "Oh my gosh Derpy! You've got an arrow sticking out of your back!" Derpy whirled around and sure enough a pixlated arrow was lodged in her back. "That must have been the impact I felt when we were running." She said calmly.
"Are you alright! I mean did it puncture anything vital!?" The Doctor was panicking slightly, ponies were fragile creatures from his perspective. Derpy calmly pulled the arrow out and it disintegrated in a shower of sparks.
"I didn't feel any pain at all, just a thump when it hit." She got a thoughtful look on her face and called up her hotbar. "Look Doctor, my health is at nine instead of ten. I don't think we feel injuries here like we would in Equestria." The Doctor checked what she said and nodded calming down, there was no wound or any sign that she had been hit.
"Now, I think we should do something about a more permanent shelter, I don't want to be stuck in a hole again." Derpy said looking around her. "We need water, for certain." The Doctor gave a small smile to himself, she was already onto the next problem and was working out what they had to do. "Does the book say anything?" Derpy asked turning to her friend. He selected the book and opened it browsing once more
"'A shelter is needed to avoid the monsters of the night (see hostile mobs).' Well that is obvious! 'to build a shelter you must create four walls and a roof.'" The Doctor turned to Derpy "I think this thing is mocking us."
Derpy rolled her eyes and looked around her. "Doctor why don't you keep browsing the book for useful information, I have an idea." The doctor shrugged and continued to flip through the pages. Derpy strode off, she had wood she could use but she didn't think it would be enough, so she turned to a hill nearby and began to dig up some of the dirt, careful to maintain a decent appearance.
When she had collected 64 she was surprised to find that another stack begun. She stopped for a moment and then decided that she had enough. She looked back at the doctor and saw him staring at the book, Derpy then headed back into the forest. It only took about a minute to reach the clearing that they had made before, she quickly found the middle and began placing blocks.
When the Doctor next looked up he could no longer see Derpy, after looking around and checking to see if she was on the other side of the hill he began calling her name. "Derpy... Miss Hooves!" The Doctor began to trot through the forest searching the sky as well as the trees. He stopped when he spotted a dirt structure, Derpy exited the building and looked it over. "There you are! I was worried, you just disappeared."
Derpy turned and smiled. "Sorry I just thought it would be nice to have a place surrounded by trees. What do you think!" She gestured grandly at the structure in front of her. It was plain, it had clearly been built to use as little blocks as possible, in the front was a 2x2 hole. "All it needs to be complete is doors and lights. Does the book have anything to say about those?"
The Doctor looked the shelter over before responding. "Apparently we can do something called crafting, all we need for doors is wood. The lights however need coal which can only be found underground." he ducked inside and viewed the small space, it was cozy yet not cramped, it was six blocks wide four blocks deep and three blocks high with two tiny alcoves in the back wall.
"Derpy, what are the alcoves for?" The Doctor asked poking his head into one.
"They are for chests." She replied placing their chest in one of them. "If we can get another one then we each can have one. Then if we can get beds then they can go in front of them."
The Doctor looked at Derpy as she walked outside again to double check her building. He was surprised, the usually gentle pegusi was taking charge and seemed to be in her element, thinking of their needs and figuring out how to make things comfortable in this strange world.
Derpy re-entered and gave a satisfied nod. "So what is this crafting thing?" The Doctor showed her how to use the 2x2 grid in her inventory and they used their new crafting table to add doors to their tiny base. To add the finishing touch Derpy used her new skills to make a sign and walked outside. The Doctor who was flipping through the book for more information on mining started to follow but was halted by a grey hoof "It is going to be a surprise."
The doctor sighed and returned to his reading. After a moment Derpy called for him to come out, as he opened the door and walked up to his assistant. She gestured for him to turn around and he obliged, above the door sat a sign which read:
