Timmy Twiddlebug

From Muppet Wiki

Timmy Twiddlebug is the son of Thomas and Tessie Twiddlebug. His sister is Tina Twiddlebug.

The Twiddlebug Family first appeared on Sesame Street in Season 5 (1973).

Timmy was first made as a Hot Pink Anything Muppet, but in his later appearances, he was a Small Orange Anything Muppet.

In his first few appearances, Timmy had a slightly different voice. Originally, Richard Hunt used a typical little boy voice, which would be even more high-pitched when speeded-up. Later skits had Hunt using a normal male-sounding voice, but would still wind up high-pitched when it was speeded-up.
