Composta Heap

From Muppet Wiki

Composta Heap is Mulch's sister and Dr. Phil van Neuter's wife.

In Episode 104 of Muppets Tonight, she appears in van Neuter's flashback to how he met his enchanting wife, set to the tune of "She Blinded Me with Science".

Composta is the Mulch puppet dressed as a woman, more or less.
