Lava Cheep Cheep

Lava Cheep Cheeps (also described as "black Tobi Lava Fish") are Cheep-Cheeps that appear in Super Mario Sunshine. Their scales are a dark mahogany color, they are constantly on fire, and they have asterisk-shaped pupils. They inhabit the magma within Corona Mountain, where they swim in one direction a short distance and then leap back to where they started in an arc. None of them are even remotely in Mario's way, however.

Trivia

 * In the Super Mario Maker series, if Cheep Cheeps are placed in lava in the castle theme, they become engulfed in flames.
