Really Gnawty Rampage

Really Gnawty Rampage is the boss level of Gorilla Glacier in Donkey Kong Country. The Kongs must beat the titular giant beaver Really Gnawty to progress to Kremkroc Industries, Inc..

Overview
Like other boss fights, Really Gnawty Rampage takes place in an arena filled with bananas. If only one Kong enters the arena, they break a DK Barrel at the start to start the fight with their partner.

Really Gnawty takes short hops across the arena and changes direction when reaching an edge of the arena. Donkey Kong and Diddy Kong can attack Really Gnawty by jumping on his head, causing him to laugh and perform a high leap (during which it is invulnerable) targeting the Kongs. For each hit, Really Gnawty moves faster and leaps further and higher. Really Gnawty also does one more large leap for each hit that he takes. The Kongs can defeat Really Gnawty by jumping on it five times, causing the boss to gasp and collapse to the ground. The Kongs are rewarded a Giant Banana.

In the Game Boy Advance remake, Really Gnawty does not perform high jumps aiming for the Kongs after being jumped on, and instead jumps to the opposite side of the arena once, causing stalactites to fall from the ceiling; Really Gnawty remains invulnerable and laughs mockingly until all the stalactites fall to the ground.
