Jelly Puff

The Jelly Puff is a aggressive creature found on Atlas that was implemented in 0.8

Behavior
Jelly Puffs are deadly at close quarters, so be careful when wandering about the crashed ships. They seem to be attracted to the radiation, so the stronger the emissions, the more likely you'll run into one of these guys. They are able to float like a jelly, and puff up and explode like a puffer fish.

Biology
Jelly Puffs have a dome shell with large spikes on the edges, 8 legs, 2 claws.

Survival
Jelly Puffs spawn inside crashed ships and will attack players on sight
