Really Gnawty is a giant Gnawty and the fourth boss of Donkey Kong Country, and he is fought at the end of Gorilla Glacier in Really Gnawty Rampage. Really Gnawty's name is a pun on "really naughty", similar to Very Gnawty's name being a pun on "very naughty".
Although Donkey Kong or Diddy Kong only need to jump on Really Gnawty five times to defeat him (just like Very Gnawty), this beaver boss is more difficult than the previous one. Not only does Really Gnawty horizontally jump even faster and farther than Very Gnawty (and he gets even faster and farther with each hit as well), Really Gnawty can also jump extremely high vertically. Once Really Gnawty gets hit, he makes a surprised expression. Then, he laughs and jumps high in the air, attempting to crush the Kongs from above, and he adds another high jump for each additional hit.
In the Game Boy Advance remake, Really Gnawty is recolored slate gray and is larger than in the original game. In the remake, when Really Gnawty is jumped on, instead of jumping at the Kongs, Really Gnawty jumps to the other side of the arena once, causing stalactites to fall to the ground.
