Don Zunāna

Don Zunāna is a giant fish in Donkey Kong Country: Tropical Freeze, found in an apparent dead end near the beginning of Amiss Abyss. The area is shrouded in darkness, rendering Don Zunāna initially invisible. However, scattering a nearby school of bioluminescent fish with a Corkscrew will light up the surroundings and reveal Don Zunāna sleeping in a grotto in the background. Don Zunāna immediately wakes up and collapses the wall on the right, then retreats deeper into the grotto, disappearing completely. With the dead end destroyed, the Kongs can proceed through the level as normal. A Blue Finley resides in the same area and will be killed by Don Zunāna during the motions, unless it was defeated beforehand.

It appears that Don Zunāna's area resets after reaching a certain point in the level, as going back to the room after reaching a certain point reveals that the wall is back. Striking a school of bioluminescent fish will reveal Don Zunāna sleeping in the same spot he was at before waking up. Unlike previously, however, Don Zunāna will not wake up.
