The Legend of Zelda: Link's Awakening is well-known for using Mario elements to a much greater degree than other Zelda games, featuring e.g. Goombas and Piranha Plants as enemies, a Yoshi doll as an item, etc.

However, one enemy reference to the Mario series is much more obscure than the others. The goo enemies in the Color Dungeon, found in the DX version for the Game Boy Color and in the Nintendo Switch version, are actually supposed to be the rare Boo Blah enemies from Yoshi's Island.

Left: a Boo Blah as seen in Yoshi's Island. Middle: a goo enemy in the Game Boy Color version (called a "Camo Goblin" there). Right: the same enemy in the Switch version (called a "Goo Specter" there).

In addition to an extremely similar appearance, their Japanese name ビヨーンおばけ (Biyon Obake, "stretchy ghost") is identical to the Japanese name of the Boo Blah in Yoshi's Island, confirming that they are supposed to be an intentional reference to that game. Note that while Yoshi's Island was not yet released at the time the original Game Boy version of The Legend of Zelda: Link's Awakening came out, the DX version was released in 1998, 3 years after Yoshi's Island.
