Toothberry

Toothberries are blue furball-like enemies that appear in Donkey Kong Country Returns and its Nintendo 3DS remake, Donkey Kong Country Returns 3D. Their name is a portmanteau of tooth, referring to their razor-sharp teeth and means of attack, and berry, as their color scheme matches that of common berries.

Toothberries attack the Kongs by jumping at them and then biting with their sharp fangs. They make a growling noise similar to that of a puppy. Donkey Kong can defeat a Toothberry by jumping onto it. Toothberries make their first and most notable appearance in the level Itty Bitty Biters, where countless of them appear out from the walls, statues, and floors. They also appear in Clingy Swingy.

Toothberries have a red variation, Acks, which are more aggressive, have a higher jump, and take two hits to defeat. Toothberries have two other variants, AckStacks and Cageberries. AckStacks are yellow variations of Toothberries that appear in groups of five, and are stacked on top of each other like a pillar. If the Kongs force them to attack, they dive down to the ground and become vulnerable to jump attacks. Cageberries are simply Toothberries that are trapped in a cage.

Trivia

 * The concept artwork of a Toothberry depicts it without a nose, while its official artwork and in-game models have a visible snout.
