Growmebas are rare enemies in the Wii video game Super Paper Mario. They are only found in Gloam Valley (along with their Catch Card) and in the Flipside Pit of 100 Trials. They look like dripping orange squares with a single round eye. Growmebas spawn clones of themselves in order to attack Mario and crew. Destroying the original Growmeba causes the clones to disappear as well. The original can be told apart by the concentric circles that appear and disappear in its eye (but not in the clones' eyes). Their name comes from "grow" (as its numbers grows), and "amoeba", a single-celled organism that can multiply at an intense rate. There's also an enemy in Megaman 10 that's acts the same to it.
