Harper asks Theo if he’s into that sort of thing, and he says that he is, but is currently looking over some sketches that he had made. Theo lets Harper look at them, seeing numerous redstone contraptions and several player skins, but she soon notices that some of the sketches resemble the four mobs that she and her group had fought in the dungeon when playing Minecraft. Theo takes the book away as he imagines a car honking at him and runs off, leaving Harper to wonder how Theo knew about the mobs. Later, in the computer lab, Harper, Morgan, Jodi, Po, and Ash assist Doc with setting up terrariums. Each of the terrariums has a single flower, enclosed in space that uses artificial sunlight as well as a precise amount of water once a day.
