From the Super Mario Wiki
A Clawdaddy is a foam-covered crab that inhabits the jungles of Yoshi's Island. They take three Eggs or a Ground Pound to be defeated. Clawdaddies rush towards a target once the target is spotted, then enlarge one of its claws before lunging and pinching, or spinning it around.
Clawdaddy teams up with Prince Froggy during the events of Tetris Attack.
In Yoshi's Island DS, they are replaced by a very similar enemy, Crabbles.
However, Clawdaddies reappear in Yoshi's New Island, this time on Egg Island.
