Nep-Enut

Nep-Enuts (Japanese version: Big Unbabas (Blue) (ビッグウンババ(あお) Biggu Unbaba (Ao))) are blue, water-based Gargantua Blarggs that hide underwater in the games Super Mario World 2: Yoshi's Island and Yoshi's Island DS. Yoshi has to throw an egg in the Nep-Enut's mouth to make it stop following him. They were supposed to appear in Paper Mario but were scrapped as development went on.
