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
The first appearance of Gnawties is in the game Donkey Kong Country, where they are divided in two separate sub-species. Green Gnawties are among the most common and weakest of enemies. These Gnawties 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 most attacks. Brown Gnawties, on the other hand, are rather uncommon, being present in only Millstone Mayhem and Temple Tempest. They navigate 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.

Very Gnawty and Really Gnawty, two bosses from the game, are notable members of the Gnawty species.

The Game Boy Advance version makes all green Gnawties blue, matching their Donkey Kong 64 appearance, and swaps Very and Really Gnawties' colors.

In Donkey Kong Country 2: Diddy's Kong Quest, Neeks seem to replace the green ones, being short rodents that attack by simply walking forward. Donkey Kong Country 3: Dixie Kong's Double Trouble! again replaces them with Sneeks.

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 the Nintendo 64 game Donkey Kong 64. Here they are commonly found in the area Jungle Japes and around Donkey Kong Island. Gnawties are also, rarely found in the area Crystal Caves. These Gnawties could be defeated by simply hitting them with any type of attack. Gnawties serve as the weakest, most easily defeated enemy of the game, and were featured in the K. Rool Arena in Jungle Japes, "Beaver Brawl". 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. There is also an unlockable game in which the player as Rambi the Rhino has to beat as many Gnawties as possible before the time limit reaches zero. In this game, Gnawties can be either light blue-colored or gold-colored. The latter awarded a total of ten points. In the main game, however, they are only blue, except for in the secret ending.
