Gnawty

Gnawties, also known as Beavers, are lazy-eyed rodents and basic enemies in a number of Donkey Kong games. Their species name is a portmanteau of the words "naughty" and "gnaw".

Donkey Kong Country
Gnawties first appear in Donkey Kong Country, where they are divided in two separate types. Green Gnawties are among the most common and weakest of enemies. They wander aimlessly in one direction and are able to damage the Kongs if they run into them. However, these Gnawties can be taken out by any attack. Brown Gnawties, on the other hand, are rather uncommon, being present only in Millstone Mayhem and Temple Tempest. They use large indestructible Millstones and cannot be reached or defeated. Some of these Gnawties chase the Kongs down an enemy-trod path, while others simply attempt to block their progress by moving in a certain pattern. In the Super Nintendo Entertainment System and Game Boy Advance versions, brown Gnawties occupy the hole in the center of the Millstone, while in the Game Boy Color version, they stay on top of it.

Very Gnawty and Really Gnawty, two bosses from the game, are notable members of the Gnawty species. They are considerably stronger than normal Gnawties, as they take more hits to defeat, and generally move by hopping instead of walking. The former is colored green while the latter is brown, reflecting the colors seen in the different types of Gnawties.

On the box art of Donkey Kong Country, the Gnawty is an off-blue gray color; in game, they are green (or brown). It wouldn't be until Donkey Kong 64 that they would receive a blue coloring in-game. To match their Donkey Kong 64 appearance, the Game Boy Advance version makes all normal Gnawties blue, including the originally brown ones. Very Gnawty and Really Gnawty's colors are also swapped, though due to the aforementioned change, Really Gnawty is blue instead.

Neeks and Sneeks from Donkey Kong Country 2: Diddy's Kong Quest and Donkey Kong Country 3: Dixie Kong's Double Trouble!, respectively, display the same behavior and weaknesses as green Gnawties. This is also the case for Awks from Donkey Kong Country Returns and Dozies from Donkey Kong Country: Tropical Freeze.

Donkey Kong Land
The variety of Gnawties in Donkey Kong Land is limited to only the walking variant, which is again vulnerable to any of the Kongs' attacks. They are very common in the game, as they can be encountered in almost every setting.

Donkey Kong 64
Gnawties make a reappearance in Donkey Kong 64. Here they are commonly found in the area Jungle Japes and on the shore of Donkey Kong Island, but can also be encountered in Crystal Caves. They also form the primary enemy in the battle arena minigame of Jungle Japes, Beaver Brawl. As in their previous appearances, Gnawties can be defeated by any form of attack, including a stomp, a roll or a punch. In an area around Cranky's Cabin in Jungle Japes, Gnawties appear in increasingly large sizes, eventually rivaling the size of Very Gnawty and Really Gnawty. Gnawties are featured in the Beaver Bother minigame, where a certain number has to be herded inside a pit until the timer's cessation. There is also an unlockable game in which the player, who takes control of Rambi the Rhino, has to beat as many Gnawties as possible before the time limit reaches zero. Here, Gnawties can be either light blue-colored or gold-colored, the latter awarding a total of ten points.

In the secret ending, a yellow Gnawty scares Dogadon after Dogadon scares Diddy Kong.
