you know how the knights put a box on top of another box? i think there is a hole below the box that leads to the core, and when the knights place a new box on top of a box, they are pushing the old box down the hole. that's how supplies are delivered to the team that works at depth 29. the new box does not fall down because there are jets on the bottom of each box that make them float. the jets are deactivated if enough force is applied to the top of the box.
also it is possible that the knights are actually danny phantom and danny phantom cloned himself a lot
Dude, what are you smoking.
