Dr. Legume is the main antagonist of the Arthur episode, "Binky Goes Nuts". He appears in a dream that Binky has before copping with his peanut allergy.


Binky's allergy to all peanut products made Dr. Legume angry enough to stick Binky on giant slice of bread covered in jelly and threaten to press him with a giant slice of bread covered with peanut butter.

Bionic Bunny bursts in and wrapped up the evil peanut and his accomplice with the peanut butter slice, and flew Binky to safety.  


  • He is a parody of Planters' mascot, Mr. Peanut.
