Birdley

“FYI! FYI! FYI! FYI! FYI!”

—Birdley, Mario & Luigi: Bowser's Inside Story

Birdley is a bird owned by Doctor Toadley in Mario & Luigi: Bowser's Inside Story. Birdley is first seen sending a message to Bowser, Mario, and Luigi about the 2nd Star Cure. After that, Birdley flies away.

Birdley is seen again in Toadley Clinic, after Doctor Toadley checks Mario and Luigi's air level, but there was an air leak, and Birdley was freaked out, flying near the ceiling with the keys to the clinic, making Mario and Luigi unable to get out. Mario and Luigi hesitantly go and get him and retrieve the keys. After Mario retrieves the keys, he gives them to the Nurse who told him what Birdley did, but then, Birdley flies into Mario's overalls, and from there on, he is a guide in the game.

The latest appearances of Birdley are in the credits, and the ending of the credits. Here, Birdley carries a box with a cake in it to Bowser.
