Glimmer

Glimmer the Anglerfish is an Animal Buddy in the Donkey Kong series who first appeared in Donkey Kong Country 2: Diddy's Kong Quest; he lives in the sunken ships of Krem Quay, and is one of the few friendly inhabitants of Crocodile Isle. Like all anglerfish, Glimmer navigates through the deep sea using a light which comes out of his forehead; however, he has no teeth, which is rare for a real-world anglerfish.

Donkey Kong Country 2: Diddy's Kong Quest
In Donkey Kong Country 2: Diddy's Kong Quest, Glimmer appears in one level, his apparent home, where he aids Diddy Kong and Dixie Kong through the oily water using the bright light attached to his head; Glimmer will swim behind the Kongs at a steady pace and cannot be harmed by enemies.

Levels:
 * Glimmer's Galleon

Donkey Kong Land 2
Glimmer is absent from Donkey Kong Land 2(being replaced by light-casting barrels) but he is pictured on the game's box art, which portrays him as aiding Diddy and Dixie Kong while being chased by a Snapjaw.

Donkey Kong Country
In the Club Nintendo comic adaptation of Donkey Kong Country, Glimmer makes a small cameo appearance in one panel to help Diddy Kong and Dixie Kong through the water of Krem Quay after the two fall into it while fleeing from a Kloak; it is not shown how the Kongs met Glimmer, nor is it shown when he departs from their company.

Trivia

 * Glimmer may have been intended to appear in the now-canceled Nintendo GameCube game Donkey Kong Racing, as he can briefly be seen in the game's trailer in the scene where Diddy Kong and Tiny Kong ride a pair of Enguarde underwater.
