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.

Metroid II manual Edit
"This snail-like creature has very sticky legs and will creep along the walls and ceilings of the caverns."
- Inhabitants & Eco System of SR388 (p. 17)
- "Tsumuri are giant snail creatures that use their toxic slime as a defense mechanism. Most Tsumuri you encounter peacefully crawl around their area, only releasing toxic slime when approached. There are, however, the red Stronger Tsumuri that constantly leave behind slime trails, but even these aren’t aggressive. They’re often easily avoided or defeated. If you don’t have a clear path around them, don’t attempt to move forward without defeating them first."
- Walkthrough (p. 45)
- "If you choose to explore the high-temperature area beyond the Charge Door, you’re immediately greeted by this little fella. Tsumuri aren’t tricky enemies to deal with—three missiles and they’re done—but they can be troublesome. They coast slowly up and down walls and platforms, but if threatened, they run away while discharging an acid-like substance in their wake. Standing in that substance for more than a second causes you to take continuous damage as long as you’re in it. Tsumuri’s hard shells also make defeating them difficult without an explosive weapon, in which case every encounter becomes a slow, somewhat careful endeavor."
- 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.
