Clampies are enemies in New Super Mario Bros. Wii. They are a sub-species of Clams, and therefore behave the same way as them. Clampies take the appearance of giant purple clams who constantly open and close their mouths. Players can find Coins and even 1-Up Mushrooms inside their mouths. Players can collect the Coins, but with caution. This is because it can close its mouth on them, making them lose a form (or kill them if small or Mini Mario). Some Clampies fall from the sky, and into the water in World 1-4 of World 1. In fact, they first appear in World 1-4 and appear in a secret area in  of World 4.
