Mecha Cheep

A Propeller Cheep-Cheep is a species of Cheep-Cheep that first appears in New Super Mario Bros. U. They appear only in the level The Mighty Cannonship. They have the form of a robot-like Cheep-Cheep, with metal fins and a propeller at the back. They're impervious to Fireballs, but can be defeated with an Iceball or Star, or by leading a Missile Torpedo Ted into them.
