An eagle-eyed fan has finally found a fabled Metroid in Donkey Kong: Tropical Freeze. The little creature floats in the background during an underwater section in the game, hiding among the coral and other similar octopus-like creatures. While it seems like some fans spotted the little guy long ago, the Easter egg has remained in obscurity since the release.
Retro Studios has a history with Metroid as the creators of the beloved Metroid Prime series. Tropical Freeze already had another Metroid reference in the form of a more easily found Easter egg in the game already, which involved Samus’ ship in the background of a level. While Metroid Prime 4 is on the horizon, Retro is not involved with the development. In fact, nobody seems to be sure what Retro is working on.
