The Mutations are a trio of purple full-bodied Muppet monsters whose name is a parody of the singing group, The Temptations. They first appeared on episode 102 of The Muppet Show as Connie Stevens' back-up singers in "A Teenager in Love." In most of their subsequent appearances, the three would mostly be depicted as dancers rather than singers.
Except for their heights, which vary depending on who is performing them, the Mutations are otherwise indistinguishable from each other.
Although they were introduced as a group, they would also be featured individually in later appearances. Two Mutations, for example, appeared in "The Muppet Show Theme" (alongside Sweetums, Thog, and Timmy Monster) starting in the second season.
