Some Boos and a Balloon Boo.

Balloon Boos[1] are enemies that have only appeared in New Super Mario Bros., where they are only encountered in World 4-A Ghost House icon from the New Super Mario Bros. game for the Nintendo DS.. They are Boos with pink cheeks, and their tail resembles a balloon nozzle, akin to their name. The level contains five Balloon Boos; thus, only five appear in the whole game.

They appear large at first, but when looked away from, they approach to the player while expelling air and shrinking; otherwise, they stop and inflate by inhaling air at a rather slow rate, until it has assumed its massive appearance once more. Balloon Boos will continue to chase Mario or Luigi even when they have reached their minimum size. Balloon Boos can be defeated with a Blue Shell or a Mega Mushroom.
