Herb's Hummingbird Robot.
Herb's Hummingbird Robot was a robot designed by Herb on the urging of Yumi and Ulrich in The Robots. It looked like a blue hummingbird with a drill on its beak, and was designed to destroy a robot X.A.N.A. had created by destroying its internal droid brain. It did not have very good engines, and had to be thrown by Yumi herself whilst Herb operated the drill controls. The Hummingbird Robot no longer exists due to the time reversion that Jeremie activated afterwards.
