Mummies Alive! (1997)

S1E23 Kid Scarab

Scarab transforms into a child sporting a purple backpack and a backward purple baseball cap, with Heka tucked away inside the backpack. At the same time, the Mummies are serving as chaperones for a field trip at the Community Center, taking the kids on a visit to Acme Bakery. In a mischievous twist, Scarab enchants the dough, causing it to morph into a gigantic dough-boy.
