Shelmet, the Snail Pokémon. Shelmet can spit a sticky poisonous acid when attacking, and it can defend itself by closing its shell.
Cool facts about Shelmet:
- When it and Karrablast are together, and both receive electrical stimulation, they both evolve.
- When traded with a Karrablast, it takes Shelmet's helmet, deshelling it and causing it to evolve into Accelgor, the Deshelled Pokémon. Karrablast then evolves into Escavalier and wears Shelmet's armor.
