Etecoon

Etecoon are a friendly species found in the Metroid series of video games, though it can now be concluded that a majority of them are now dead following Zebe's explosion.

In Super Metroid, the creatures that oddly resemble monkeys will teach Samus Aran how to wall jump. They also appeared in Metroid Fusion, suggesting that some of them survived the destruction of Zebes, as they were found on the Biologic Space Labs, where Samus freed the creatures.
