Aubrey Molehill

From Muppet Wiki

Aubrey Molehill was the son of Gus and Glenda Molehill in the Dinosaurs episode "Switched at Birth." After the Sinclairs realized that Baby Sinclair's egg nest was switched with the Molehills' nest, evidence from the Absolute Proof laboratory suggested he was the real son of Earl and Fran.

Aubrey was green and wore a red and black checkered shirt, just like Earl. He was a bit neurotic, fussing over many minor injuries, bleeding a lot, and requiring sugar-free tofu teething cookies. While the rest of the Sinclair family was annoyed by him, Earl really liked him since he did not regularly terrorize him.
