Blue Finley

Blue Finleys are light-blue fish enemies and members of the Finley family in Donkey Kong Country: Tropical Freeze and its Nintendo Switch port. They appear in many levels, usually those that primarily occur underwater or at seaside. Blue Finleys first appear in the first level, Mangrove Cove, as the very first enemy encountered by Donkey Kong on his adventure.

Description
Blue Finleys can be found solitary or in small schools. They swim around in either vertical, horizontal, or circular patterns, as shown in Deep Keep, without trying to target the Kongs. If the Kongs swim into a Blue Finley, it bites them, therefore injuring them and taking away a Heart. A Blue Finley can be defeated by either the Corkscrew move or a cane attack by Cranky Kong.

In Rocket Rails, unlike the other levels, Blue Finleys demonstrate their ability to swim in midair. The playable Kong can defeat a Blue Finley by stomping on it. Blue Finleys may also serve as improvised platforms to get across wide chasms. One of the level's Puzzle Pieces can only be collected by jumping on a Blue Finley.

Blue Finleys have red-colored relatives named Red Finleys, who behave similarly but have the ability to travel underwater more quickly.
