My family enjoyed an Easter brunch at an Indian restaurant. The buffet included a dessert area, and one of the items there was an orange goo with this label:
Mango Moose
The restaurateur meant "mousse." That is the word for a dessert — and for the foam that people put in their hair in the 1980s.
Mango Moose may not be a great name for a dish, but it's perfect for a cartoon character.
This post would be better if you got your son to draw a Mango Moose and posted it.
