For the gourd, see Pumpkins

The Pumpkin Anything Muppet is an orange rod puppet with a long, oval-shaped head. Though sometimes referred to as "Tall Orange" in fan communities, the official name, according to a 1979 character style guide, is Pumpkin.

There is also a pumpkin live hand puppet first used in Season 35. There's also a pumpkin-orange puppet with a rounded head and live-hand, similar to the large lavender live hand puppet, but visually distinct from the typical Pumpkin Anything.
