The Wacky Races may have ended in the late sixties, but Hanna-Barbarra kept the characters alive in the two spin-off shows Dastardly & Muttley in Their Flying Machines and The Perils of Penelope Pitstop. Warner Brothers Home Entertainment will be releasing the complete series of both shows this spring.

Dastardly & Muttley in Their Flying Machines: The Complete Series follows the schemes of the Vulture Squadron to stop a carrier pigeon named Yankee Doodle Pigeon. As leader of the Vulture Squadron, Dick Dastardly would try to follow orders from the General to “stop that pigeon.” With the aid of his snickering canine sidekick Muttley, who always muttered his signature “rassuh-frazza-pazza,” and fellow dimwitted pilots Zilly and Klunk, the Vulture Squadron would use their WWI aircrafts to carry out their missions. Among the episodes featured on the DVD is Magnificent Muttley, in which Muttley decides that he’s finally had enough and flies off into his own fantasy world where he gets to be boss for a change and many others.

The set contains the featurettes Vulture Squadron’s Greatest Misses and Dastardly & Muttley’s Spin-Off’s, commentary on Stop Which Pigeon, Ceiling Zero Zero, Fast Freight, Home Run and Start Your Engines; Balmy Swami, Camouflage Hop-Aroo, Mop Up, Left Hanging and Wild Mutt Muttley by Iwao Takamoto, Designer Jerry Eisenber, Designer, Scott Awley, Warner Bros. Animation and Scott Jeralds, Warner Bros. Animation.

The Perils of Penelope Pitstop: The Complete Series puts beautiful Penelope, a Southern Belle and heiress to a vast fortune, in peril at every pit stop. In each episode, she was constantly being followed by her guardian, Sylvester Sneekly, who disguised himself as “The Hooded Claw.” His goal was to bump off Penelope by any means necessary in order to get her fortune. Facing danger at every turn, Penelope would often get help from her friends, the Ant Hill Mob, a group of seven diminutive men who would come to her rescue. Along with their car, Chugga-boom, the Ant Hill Mob would arrive in time to save pretty Penelope from peril.

The set contains commentary on Jungle Jeopardy and The Treacherous Movie Lot Plot by Janet Waldo, Voice of Penelope, Iwao Takamoto, Designer, Gary Owens, Narrator, Scott Awley, Warner Bros. Animation and Scott Jeralds, Warner Bros. Animation and the featurettes The Player in Perils and Penelope Pitstop’s Spin Outs.

Both sets arrive on May 10th for $34.98.
