Scoff

Scoff is a giant blue hippopotamus that the Kongs meet in Donkey Kong 64.

In every area of Donkey Kong 64 (except for Hideout Helm) the Kongs come across a Scoff n' Troff Portal which transports them to Scoff and his buddy Troff. It seems Troff has eaten too much and in order for him to reach the key to a Boss Door, the Kongs must feed Scoff a certain number of bananas so he can lift Troff up to the key using a see-saw like mechanism.

After the Kongs defeat King Krusha K. Rool, both Scoff and Troff retreat to DK's Tree House, where they party with the Kongs and their friends.

Trivia

 * Every time Scoff eats bananas he grows tremendous, only to inexplicably shrink later on.
