Yumbo as it appears in Metroid II.

Yumbos are small creatures that live on SR388. Samus Aran encounters them in Metroid II: Return of Samus. They fly side-to-side high overhead, so they rarely pose any sort of problem. They're very mosquito-like in appearance. The feathers along their long needle seem to rotate, giving the appearance of a chainsaw. Their rather small wings don't look as though they could support the weight of their entire bodies, but somehow they barely manage to.

"Flies unsteadily in the air."


  • Yumbo is the first creature Samus encounters in Metroid II.
  • It is unknown whether or not the Yumbo species became X Parasite hosts, as Samus did not encounter any Yumbo-X in Metroid Fusion.
  • Yumbo do not appear in Metroid: Samus Returns, the remake of Metroid II.
