Really Gnawty is a giant Gnawty and the fourth boss of Donkey Kong Country, and it is fought at the end of Gorilla Glacier in Really Gnawty Rampage. Its 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 it (just like Very Gnawty), this beaver boss is more difficult than the previous one. Not only does it horizontally jump even faster and farther than Very Gnawty (and it gets even faster and farther with each hit as well), it can also jump extremely high vertically. Once it gets hit, it makes a surprised expression. Then, it laughs and jumps high in the air, attempting to crush the Kongs from above, and it 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 it 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.
