Egg-enut

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