Egg-enut

An Egg-Enut is a hiding Caged Ghost from Yoshi's Island DS that's name strangely resembles Nep-Enut. It has a long antenna with a fake Yoshi Egg on the end and lives in Pipes or underwater. If Yoshi gets too close, the Egg-Enut will whip back his antenna and wave it back and forth, waiting until either Yoshi goes away or is hit with an egg to go back in.
