|Attack||Dangerous on contact|
|Abilities||Hiding and walking|
Shell monsters have a purple shell with a grey spike on top of it. Its purple shell covers the entire body of the monster. The monster has black legs and yellow eyes.
Shell monsters are one of the most difficult enemies to kill aside from the fish men. If a shell monster is walking and stops, anything thrown at it will act as if thrown at a wall. The monsters can only be stunned if they are hit while walking. Walking into a shell monster, or vice-versa, will kill the player.
One glitch is that shell monsters may sometimes walk through walls.
There is another glitch that happens to this monster. If a shell monster is facing the player, and it is hiding in its shell and the player shoots a block, the monster will be stunned for a few seconds, then it will move a little bit and will continue being stunned.
