Ronald Grump is a famous Grouch builder who appears in a season 19 episode of Sesame Street. Grump approaches Oscar the Grouch to build his "Grump Tower" on Oscar's property. In exchange, Oscar will get to reside in the new building, plus receive a small amount of trash. Oscar complies and the new "Grump Tower" is built. However, Oscar decides to opt out when he finds out he can't keep his pets. Grump instead asks for 40 bags of trash to move his tower. Oscar doesn't have that kind of currency, so the rest of the adults help him out and defeat Grump.
