Cageberry

Cageberries are a variant of Toothberries appearing in Donkey Kong Country Returns and its Nintendo 3DS port, Donkey Kong Country Returns 3D. They are blue enemies resembling furballs and have white fangs. Every Cageberry is locked inside a golden cage with brown bars, hence their name. They cannot be defeated by the Kongs.

Cageberries mainly appear in the Ruins world. Although they are trapped in their cage, Cageberries can still move by pushing it around. Their cage is pointed on top, so if Donkey Kong and Diddy Kong jump on it, they get injured and lose a heart point. Cageberries mainly attack by pushing their cages towards the Kongs. Donkey Kong can Ground Pound near the cage to flip it over, and can perform another ground pound on top to sink it into the ground. This causes the cage to briefly pop up and function like a trampoline; after a while, if a Cageberry is flipped over, it gets back up. If Donkey Kong and Diddy stand on the cage when the Cageberry gets up, they get boosted into the air.
