94Ms. Frizzle and the Magic School Bus are set to release two all new DVDs—The Magic School Bus: Revving Up and The Magic School Bus: In A Pickle.

The Magic School Bus: Revving Up will feature 12 never-before-available episodes. Each of the three discs in the set—”Under Construction,” “Getting Energized,” and “Cracks a Yolk”—contain three new episodes running the gamut from computers and electricity to city critters and desert adaptation. Also, each DVD also contains a special bonus episode adding up to more than four-and-a-half hours.

Viewers who hop aboard the bus for The Magic School Bus: In A Pickle find out about peculiar smells across four never-before-released episodes including the title episode about microbes, “Meets Molly Cule,” “Makes a Stink” about smell, and “Meets the Rot Squad,” which covers decomposition.

The DVDs will be available July 30.
