Mumbo is a species on SR388. It flies with the same pattern and rate as the Pincher Fly, but it causes slightly more damage to Samus Aran through physical contact. It is an enemy encountered in Metroid II: Return of Samus and Metroid: Samus Returns. In the latter, it is now a swarming creature that can overwhelm Samus, and inhabits superheated rooms in Areas 3 and 4.
"This enemy flies in the air."
- Oddly, the Mumbo's face rather resembles Samus' helmet.
- It is unknown if they became X Parasite hosts, as Samus did not encounter any Mumbo-X in Metroid Fusion.
