Clampy

A Clampy is an enemy in New Super Mario Bros. Wii. They appear in World 1-4 and a secret area in World 4-1. They trap characters in their mouths, giving them damage, and then releasing them. Most of them have Coins in their mouths to attract players to them.

Clampies can be seen in Cheep Cheep Lagoon in Mario Kart 7. Similar to New Super Mario Bros. Wii, Clampies have items in them to lure players toward them, such as Item Boxes.
