Albatoss

An Albatoss is a red bird and an enemy in Yume Kōjō: Doki Doki Panic and its western counterpart, Super Mario Bros. 2. Their name is a portmanteau of the "" bird species and "toss," which refers to their attack method.

Super Mario Bros. 2
In Super Mario Bros. 2, Albatosses used to be normal residents of Subcon until Wart took control. Albatosses carry Bob-Ombs and drop them, attempting to hit one of the playable characters: Mario, Luigi, Princess Toadstool, or Toad. An Albatoss can be defeated if the player's character throws a vegetable at it or touches it under the Starman effects. Unlike most other enemies, Albatosses cannot be picked up and thrown.

If an Albatoss flies low enough, the character can jump on an Albatoss's back and ride on it. World 6-2 and World 7-1 require the player's character to ride Albatosses to reach otherwise inaccessible parts of the level; these ones do not carry Bob-Ombs.

Super Mario Bros. 3 remakes
In the SNES and Game Boy Advance remakes of Super Mario Bros. 3, the King of The Sky is turned into an Albatoss (in the original version, he is turned into a vulture).

The Super Mario Bros. Super Show!
Albatosses make a few appearances in The Super Mario Bros. Super Show! They are usually used as bombers by King Koopa, and they sometimes capture Mario and company in nets. Albatosses are also seen in the show's intro.

In the episode "Jungle Fever", Mario and his friends ride an Albatoss to get off of the bridge King Koopa sliced. Moon Man Koopa's spaceship also resembles the head of an Albatoss. Additionally, the character Hooded Robin somewhat resembles an Albatoss.

Super Mario-Kun
In a part of Super Mario-Kun, an Albatoss is carrying Mario, Luigi, and Yoshi but then hurls them into a wall.

Trivia

 * In Yume Kōjō: Doki Doki Panic, Albatosses move at two frames, while in Super Mario Bros. 2, they move at seven frames; an eighth frame exists, showing the wings moving back upwards but is unused due to a glitch. The Super Mario All-Stars and Super Mario Advance remakes restore the missing frame.
