Gamet

Found on Zebes, these little pests are a lot like Zebs and Geegas. They live in small air holes in the ground, just waiting for their prey to come near, then they come out of the pipe as a swarm and attack the foe in a type of vertical formation.

Metroid Manual
Their bodies are covered by a super-hard shell. They fly out of the air holes and attack Samus. The reds [sic] ones have twice the strength as the others.

Captain N
A single Gamet appeared in the episode "Metroid, Sweet Metroid", attacking Kevin when he was trapped on Metroid (asteroid). It made a sound like a bird call as he dodged it. Unlike normal Gamets, this one turned around when it missed, followed by a Skree.
