Solve It with Scooby-Doo!: Math[]
Her doughnut shop business was being troubled by a ghost that they dubbed as the Balmy Baker, a dusty white spirit who had been sneakily subtracting certain amount of pastries from customers boxes when they ordered, example being Mrs. Puff getting only two cookies in her box instead of six.
She explains to Mystery Inc. about the happenings and the Bakers responsibility, who had been breaking into her store's storage room to steal the pastries. She then leads them to the room to show some footprints it left behind, originally being eight, but three were cleaned up upon. Until the two gluttonous cowards of the group licked the footprints, revealing that they were made of powdered sugar.
She went to the counter and gotten a phone message from one customer, Mr. Flaky, that his box of twelve doughnuts had four doughnuts missing, this left her upset that she had to replace another order, but got reassured from Fred that he and the gang will spring a trap on the Baker when it comes back.
She got to witness the gang catching the baker with a flour sack during it's attempted escape through the front door, and it was unmasked to be Carolina Cupcake, the owner of the Plunkin' Pastries. She had been trying to ruin her business with the thefts and break-ins so people would stop going and head to her bakery instead.
