Lifepod 5 from Subnautica. I tried my best to make it the closest medium between its source material and a functional base in Minecraft. Feel free to extract the pod and transfer it to other worlds. If using structure blocks, be sure to include entities, and be careful when placing it, as there tends to be a slight flooding issue. The storage container located in the front of the pod contains some custom water gear, as well as a knife, a compass, and a PDA journal. Feel free to use them if you wish.

You will spawn in the water outside the pod in survival mode! Swim or you may drown!
