Grim Leecher

Grim Leechers are enemies from Super Mario World 2: Yoshi's Island, its remake, Yoshi's Island: Super Mario Advance 3, and Yoshi's New Island. These enemies resemble purple ghosts with skulls on their faces, and their name is a pun on the "Grim Reaper" and "Leech". If Yoshi is a good distance from a Grim Leecher, they will wait until Yoshi comes near, and then hover towards Yoshi once he comes too close. If they come in contact with Yoshi, the Grim Leecher will kick Baby Mario off Yoshi's back and hop on. This will cause the game controls to reverse, and Yoshi will be colored pink, although in Yoshi's New Island the Yoshi will be colored purple. They are referred to as "Purple Zombies" in Super Mario World 2: Yoshi's Island ' s pocket guide.
