Mite did not originate from fanon, and the information on this page may not be entirely accurate to their canon. You may read more about this subject in the context of their canon on the following wiki(s):
Mite is a yellowish orange mole-like enemy in Kirby 64: The Crystal Shards. He has a round body with round black eyes, what appears to be a white beak, and long arms and legs with sharp, triangular claws. Mite is often seen digging out of the ground and just running around everywhere pretty fast before digging back underground. He gives no ability when inhaled. If Mite is held above Kirby's head he will flail around, but when he is thrown he will fall down and burrow underground unharmed.
