The Yogmans

Lenny Yogman (voiced by Josh Peck) and Denny Yogman (voiced by Austin Stout) are fraternal twins that are rarely seen attending class. Instead they are in the laboratory located in the school's H.V.A.C. system. They wear red hats that resembles the 1980s band Devo's energy dome hats, yellow shirts, and black sneakers. Lenny is the taller twin and Denny is the shorter twin. They have occasional victories and occasional defeats. When defeated, they end up hissing much louder than they normally do. In the Robot Jones promotional, The Yogman Twins are said to be one of the antagonists with the mission to destroy Robot Jones.
