The Magic School Bus - Meets Molly Cule - Ep. 45

Wanda's favorite singer, Molly Cule (Wynonna Judd), is coming to Walkerville. Wanda wants to have the great honor of washing her car. The class sets up a car wash. She miraculously chooses theirs over automatic car washes. The reason for this is explained when she says that she can't afford to have her hood ornament get wet. When Arnold asks what it's made of, she says, "That's my little secret, Sugar." She continues to call him "Sugar" for the remainder of the episode. After they clean the car, she found a tiny blot of tar on the hood using a "megamagnifier." They shrink down to the size of molecules to find it, and clean it off. However, when they get back, Wanda accidentally knocks Molly's hood ornament into their bucket of water. It occurs to Arnold that it is made from sugar, from what she said when he asked her what it was made from. The class shrinks down to the size of molecules again to rebuild it. After they start, the sugar molecules begin to crystallize and it gets put back together before Molly returns. They then get to participate in her concert.
