Yumbos 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.
Metroid II manualEdit
"Flies unsteadily in the air."
- A Yumbo is the first creature Samus encounters in Metroid II: Return of Samus.
- Yumbos behave identically to Meboids, Mumbos, Pincher Flies, Seerooks, and TPOs. Their shared behaviors may explain why Yumbo and Mumbo have similar names.
- It is unknown whether or not the Yumbo species became X Parasite hosts, as Samus did not encounter any Yumbos in Metroid Fusion.
- Yumbos do not appear in Metroid: Samus Returns, the remake of Return of Samus.
