Toucan't is an enemy in Donkey Kong Country: Tropical Freeze. They are a small, possibly flightless toucan riding around on a cactus ball that emits spores. It can be killed by jumping on its head. You cannot roll into it because the cactus ball will hurt you.
Toucan'ts resemble a regular sort of toucan, with a red, yellow and green beak, green and yellow body and yellow feet. It's feet must have strong endurance to not be harmed by the cactus ball. It's possible that it is called a Toucan't because it either can't fly or because generally, you wouldn't be able to defeat it.
