Chowder (2007)

S02E16 Kid Schnitzel

Shnitzel grows weary of his grown-up duties and opts to embrace his inner child, much to Mung Daal's annoyance. In a twist, he hands over his responsibilities to Chowder, who in turn chooses to regress to a baby-like state. This playful rebellion leads to Shnitzel mimicking Chowder, prompting Mung to take drastic action by sending them both to the baby pound.
