Mr. Ruhle, voiced by the late Paul Winfield, is the Principal of Walkerville Elementary. He once ran a bet with Ms. Frizzle on whether or not she could beat the light pinball machine she and Liz had built (Makes a Rainbow). He is an expert on chickens, owning a Rhode Island Red rooster named Giblets, who Dorothy Ann had accidentally lost in Cracks a Yolk.


  • His serious demanour, appearance, and voice sounds a lot like Professor Oglevee from The Parkers
