Pidgit
A Pidgit is a small black bird found in the game Super Mario Bros. 2. Pidgits are unable to fly on their own and thus they use a magic carpet to soar through the skies of Subcon. To attack, a Pidgit will attempt to fly into Mario or one of his friends. Thus, Mario should jump on top of the Pidgit during its descent and thrown it off the magic carpet. Mario can then ride the magic carpet for short distances. Often, Mario needs to use these magic carpets to reach inaccessible parts of certain levels.
Starting in Super Mario World, the enemy known as Lakitu seems to have absorbed the characteristics of Pidgit, making the bird somewhat obsolete. A Lakitu rides in a smiling cloud, and if Mario can somehow defeat the Lakitu, its cloud will be left behind. As such, if Mario jumps in the cloud, he can use it to fly through a level for a short period of time (just like Pidgit's magic carpet).
However, Pidgits recently appeared as common enemies in Mario and Luigi: Partners in Time. They are located on Yoshi's Island.
Additionally, Pidgits appear in Wario's Woods.
In Super Mario World, if Mario or Luigi clear all the levels of the Special World, Bullet Bills will be changed to resemble Pidgits and be renamed Pidgit Bills.
Pidgits make a cameo appearance in Super Smash Bros. Melee. They appear in the level Mushroom Kingdom II: Subcon and ride magic carpets. Interestingly, while its magic carpet is three-dimensional, the Pidgit is a two-dimensional sprite.
Bill the Extra Guy, from the widely successful Mario parody the Neglected Mario Characters sprite comics, is a Pidgit.
