Egg-enut

An Egg-enut is a small species of Nep-Enut with a long antenna that has a fake Yoshi's Egg on the end. It only appears in Yoshi's Island DS. It lives in Warp Pipes or underwater, and if Yoshi gets too close, the Egg-enut will whip back its antenna and wave it, waiting until Yoshi either goes away or hits it with an egg, making it go back into its dwelling.
