Bobo the Rabbit

Bobo the Rabbit is the rabbit that Heinz Doofenshmirtz used in his magic act when he was in 7th grade. Doofenshmirtz was unable to pull him out of his hat, but instead accidentally pulled out a skunk. After that event, Heinz looked for Bobo until his adulthood, wherein he found him with the help of Perry the Platypus when he tried to perform magic again. Perry had made Bobo appear when he shot him out of Heinz's hat. Heinz then remarks,"Bobo the rabbit, did you know I've been looking for you since the 7th grade?" Perry proceeds to shoot hundreds of Bobo the Rabbits out of the hat (as if from a machine gun). ("Leave the Busting to Us!")
