Smart etecoon
Etecoons and Dachoras. I've met these intelligent beings before. They seemed to recognize me, as well. How unusual to meet again here. In the past, they've helped me unleash abilities I didn't know I had. But where did they run to? I hope they're safe...

—Samus Aran

Etecoons are blue, monkey-like creatures that inhabited the planet Zebes, and one of only three non-violent species Samus encountered there. In Super Metroid, these rather intelligent mammals taught Samus how to Wall Jump to reach greater heights. When Samus enters their room, they sing the Samus Victory! theme, before teaching Samus the Wall Jump. Later in the game, they are trapped along with the Dachora in the room where Samus fought the Torizo. Samus is able to save them by shooting out the wall so they can escape, and they flee Zebes using a spacecraft.[1]

Additionally, in Metroid Fusion, Samus rescued these same Etecoons and Dachoras from the Biologic Space Laboratories research station, when the X Parasite took over. These beings learned to control Samus's ship with the help of her on-board computer and commander, Adam, and helped her escape the destruction of the station and neighboring planet of SR388.

Metroid Prime 3: CorruptionEdit

Though Etecoons do not appear in the game, files are present for an unused Logbook entry for a similar creature called an Endocoon. No models, textures or scripts exist for it in the game's code, but the room Xenoresearch Lab, on the G.F.S. Olympus, is named "04_gfship_endocoonlab" in the game's code, presumably indicating they were to appear there. The room's counterpart, on the G.F.S. Valhalla, is correspondingly named "04_abandoned_endocoon".

Unused Metroid Prime 3: Corruption Logbook entryEdit

Morphology: Endocoon
Threat level low. Fond of machinery. Widely considered to be cute.

Logbook entry

Endocoons are a semisentient species of mammal known for their playful demeanor. They are particularly fond of machines, perhaps drawn by the hum of an engine or the shine of metal. Unfortunately, their inquisitive nature can be quite disruptive, especially when fine machinery is involved.



  • Although it is stated in Metroid Fusion that the Etecoons teach Samus to Wall Jump, she has this ability in Metroid: Zero Mission, Metroid Prime 2: Echoes, Metroid Prime 3: Corruption and Metroid: Samus Returns, all of which chronologically happen before Samus first encounters the Etecoons in Super Metroid.
  • These creatures are one of the very few species of mammals to exist in the Metroid series of games. Other notable mammals are humans, the Rabbilis and the unused IceBoss.
  • On the storyboard to the right, it says there are four of them. However, only three are ever shown in both Super Metroid and Metroid Fusion.
  • Also on the storyboard, it says they live in "Hell". This may also be a reference to their nearby habitat; filled with specific thorny-like substances and unique enemies. In addition, their "home" is somewhat deep underground.
  • The Etecoons are a greenish color in Super Metroid, but blue in Fusion and artwork.
