Lenny the Lizard is a turquoise lizard with yellow ping pong ball eyes, black eyelashes and pointy teeth who often performed with the monsters and Frackles. He bears a passing, although somewhat sinister, resemblance to Kermit the Frog.
In fact, Lenny substituted for Kermit in two appearances on The Muppet Show, first in the "Inchworm" sketch that Kermit made famous on variety shows in the 1960s, and later when he auditioned for the role of the show's emcee in episode 208.
Lenny had no consistent performer. His known performers include:
More recently, Lenny was given his own page in The Muppets Character Encyclopedia.
