Mel Spankenheimer is a gold digger who attempts to get Grandma Spankenheimer to sell her store, she wears too much jewelry and beats Grandpa at cards.
Mel wanted to sell the store to Austin Bucks, the wealthiest man in the town of Cityville, but Grandma refuses. Mel planned to add a vial to the fruit cake badder, so people will stop coming, forcing Grandma to sell, however, the scent attracted Santa's reindeer where Grandma was run over by his sleigh. After her disappearance, Mel hid a letter from Santa for about one year to keep her family and the rest of the town in the dark about it. Mel than tricked Grandpa into signing power of attorney to her. When Jake and Santa brought Grandma, Mel and her lawyer, I.M. Slime, kidnapped her thus making Santa the fall guy in a lawsuit for all his money. However, with the help of Jake, she was exposed and confessed in court during Santa's trial, arrested for obstructing justice and almost ruining Christmas.

Mel doesn't care about the well-being of her family. She'd showed no sympathy when the family was distraught over Grandma's disappearance, tricking Grandpa into signing power of attorney to her so she can sell the store, and kidnapping Grandma while she had amnesia.
