Mimosa Infesta is a giant carnivorous plant that functions as the third boss of Teenage Mutant Ninja Turtles: Dark Horizons. It is accompanied by mutant mushrooms.

It is unknown if Mimosa Infesta is a game-exclusive character, or will later show up elsewhere.

Its name comes from Mimosa, a plant genus, and infesta, a Latin, Spanish, Italian, and French word for infestation.
