Tsumuri as it appears in Metroid II: Return of Samus.

A Tsumuri is a creature found in Metroid II: Return of Samus. It has the same artificial intelligence as a Zoomer, which it somewhat resembles (although it has a single sticky, snail-like foot instead of the Zoomer's multiple jointed legs). It is found early on in the main tunnel and in the vertical shaft next to the second Chozo building.


"This snail-like creature has very sticky legs and will creep along the walls and ceilings of the caverns."


  • Their name may have been derived from tsunamis.
  • They rather resemble Zoomers, and in fact, their name seems to be a rough derivation of that creature's name.
  • It is unknown whether or not the Tsumuri species became X Parasite hosts, as Samus did not encounter any Tsumuri-X in Metroid Fusion.
  • In Metroid: Samus Returns, the Tsumuri is seen in a superheated room, suggesting it is accustomed to that kind of climate.
