Cheep-Cheep are fish that made their first appearance in HTF Adventures. They are common recurring enemies throughout the HTFA series. They are found mostly in the water, but they can jump out of the water. There are many different species of Cheep-Cheeps, and they come in different colors, including yellow and green. The most common ones, however, are red with a white patch on their stomach, a yellow (originally white) tail fin, a mohawk-like dorsal fin and wing-like fins. They also have blue eyes and pink lips. Cheep Cheeps have fins shaped like wings and may attack above the surface of the water by jumping out in an arc. Given this, Cheep Cheeps seem to be inspired by flying fish, who behave similarly.
