Glimmer the Angler Fish
“Glimmer lives in one of the sunken Kremling galleons near Krem Quay. He'll offer his light to show the Kongs the way through one of the darkened underwater levels.”
Glimmer the Angler Fish is an Animal Friend in the Donkey Kong franchise, 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 series
Donkey Kong Country 2: Diddy's Kong Quest
In Donkey Kong Country 2: Diddy's Kong Quest, Glimmer only appears in Glimmer's Galleon; 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.
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 Lockjaw.
Donkey Kong Country
In the Club Nintendo comic adaptation of Donkey Kong Country 2, 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.
