小嘴蝸

Black: When attacked, it defends itself by closing the lid of its shell. It can spit a sticky, poisonous liquid.

White +2: It evolves when bathed in an electric-like energy along with Karrablast. The reason is still unknown.

Black 2 +3: When it and Karrablast are together, and both receive electrical stimulation, they both evolve.

Sword: When attacked, it tightly shuts the lid of its shell. This reaction fails to protect it from Karrablast, however, because they can still get into the shell.

Shield: It has a strange physiology that responds to electricity. When together with Karrablast, Shelmet evolves for some reason.
