Penguins
The Penguins are mostly nameless and undifferentiated from one another. Generally playful and wacky in nature, they have appeared in many Muppet productions (sometimes in places where penguins are not commonly seen). They are best known for tossing themselves into the air. The Muppet Penguins usually communicate with sounds that penguins would make, but they have spoken a few times. In The Muppets' Wizard of Oz, the Muppet penguins are referred to by Scooter as "unisex" (gender androgynous or applicable to male and female), reflecting the fact that they function as a collective, identical and indistinguishable.read more
