In Click Clock Wood, a beaver named Gnawty can't get to his house because a boulder blocks the path. Gnawty resembles the beaver enemies of the same name in Donkey Kong Country, another game developed by Rare.

Gruntilda's quiz game contains an obvious Donkey Kong reference. One question asks, "In Mumbo's Mountain you don't know, What does that big gorilla throw?" Of the three answers you can select, one of the incorrect answers is "Barrels."
