Seagull

Seagulls, or simply gulls, are real life birds that have appeared with gameplay roles in several Mario-related games.

Wario Land II
In Wario Land II, gulls first appear in the level Get in the Tea Cup. They are harmless and are found flapping their wings in one place in midair. Wario can use them as platforms to reach remote locations; however, they fly away before long once he touches them but come back shortly afterwards. Like the game's enemies, gulls can be killed with a Dash Attack or a ground pound, respawning only if Wario leaves and re-enters their area.

Game & Watch Gallery series
Seagulls, here identified as albatrosses, appear in the Modern version of the Game & Watch title Donkey Kong Jr. in Game & Watch Gallery 3 and Game & Watch Gallery 4. In these games, when Donkey Kong Jr. gets the key on the second stage, an albatross appears and acts as a platform so that he can reach his father's cage. Unlike its Wario Land II counterpart, the albatross does not fly away when Donkey Kong Jr. touches it. However, it does regularly fly away for a short time, forcing Donkey Kong Jr. to time his jump carefully. An albatross also occasionally appears in the background of the Modern version of Fire from Game & Watch Gallery 4.

Mario Party 8
Seagulls appear in Mario Party 8 on Goomba's Booty Boardwalk. If Captain Goomba gives a Star to a player, he will order seagulls to transport the player to the beginning of the board. Seagulls can also be seen flying in the background of the board.

Super Mario Odyssey
Seagulls also appear in Super Mario Odyssey in the Seaside Kingdom. Much like little birds and other wildlife found in this game, they initially stand on the ground, and fly away if Mario approaches them.
