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 Yoshi either goes away or hits it with an egg to go back into its dwelling.
