Really Gnawty

Really Gnawty is a giant Gnawty and the boss of the Gorilla Glacier in the game Donkey Kong Country. He is the fourth boss in the game. Although Donkey Kong or Diddy Kong only need to jump on top of Really Gnawty five times to defeat him (just like Very Gnawty), this beaver boss is a lot harder than the previous beaver boss. Not only does Really Gnawty horizontally jump even faster and farther than Very Gnawty, Really Gnawty can also jump extremely high vertically. In battle, after Really Gnawty gets hit, he will jump high in the air, attempting to crush the Kongs from above. Thankfully, he will only do this a certain number of times after each hit: after he is hit the first time, he jumps high once, after he is hit the second time, two high jumps, third time, three jumps, etc. And, just like Very Gnawty, Really Gnawty hops progressively faster and farther after each hit, making this battle extremely tough. However, after five hits, Really Gnawty collapses just like Very Gnawty.

In the Game Boy Advance remake of Donkey Kong Country Really Gnawty loses his high jump attacks for new attack: he'll jump all the way to the other side of the screen and slam into the ground, causing fragile stalactites to fall to the ground.

Really Gnawty is a palette swap of Very Gnawty. While Really Gnawty has brown fur, Very Gnawty has gray fur. In the GBA remake, this was reversed.

Really Gnawty is an obvious pun on "really naughty", like Very Gnawty is one of "very naughty".
