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 (Etekon in the Metroid Fusion debug data) 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]

The Etecoons and Dachoras appear again in Metroid Fusion, on board the Biologic Space Laboratories research station as the sole survivors of the X Parasite infestation. They are found on the Habitation Deck, confined in a sealed, tropical themed area with hanging tires for the Etecoons to play on. It is unknown why these creatures were on board, or why the X did not target them as potential hosts, though Adam suggests the creatures had no useful capabilities for the X. After Samus released them, the Etecoons and Dachoras went to Samus's Gunship, and they later saved Samus from the space station's explosion after the defeat of the Omega Metroid by piloting her gunship into the room to rescue her.

Non-canon warning: This article or section contains information that may not be considered an official part of the Metroid series in the overall storyline by Nintendo.

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".

Metroid Prime 3: Corruption

Temporary scan

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.

Super Metroid Developer InterviewEdit

Akinori Sao: Yamamoto-san, what part of Super Metroid do you recommend?

Yamamoto: This is a bit detailed, but after you beat the last boss, Mother Brain, Samus escapes, right? The planet is beginning to explode, so you really have to hustle. But at a certain spot, there's a Dachora and some Etecoons…

Sakamoto: Dachoras and Etecoons are alien creatures who teach Samus new moves, and they've gotten trapped while trying to evacuate.

Sao: If you help them, the ending changes. Is that right?

Sakamoto: The ending doesn't exactly change, but when the planet explodes and Samus just barely clears the blast in her ship, out to the side you can see…

Yamamoto: The Dachora and Etecoons escape, too.

Sakamoto: About one dot of light shoots out from the exploding planet! (laughs)

Sao:(laughs) You understand from that one dot of light that they survived.

Sakamoto: I tried it myself, and the dot was so small I could barely see it! (laughs)

Sao: Is that because it was an old tube TV?

Sakamoto: Yes. With the high resolution screens today, you should be able to see it clearly. I hope people will check that out for themselves.

Yamamoto: There may also be people who played Super Metroid before who don't know about that. I hope they will play the game again and help those creatures! [2]


  • 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.
  • The Super Metroid Players' Guide refers to the Etecoons as the "three little creatures".
