|“||Hey! I deserve to be rich!||„|
|~ Cousin Mel boasting herself.|
Cousin Mel (simply known as Mel) is the granddaughter of Grandma and Grandpa, the older cousin of Jake and Daphne, the niece of Mr. and Mrs. Spankenheimer and the main antagonist of the children's animated Christmas special, Grandma Got Run over by a Reindeer (which features the song after which it is named).
Mel is a golddigger who wants to sell Grandma's store to Austin Bucks, the wealthiest man in the town of Cityville, but Grandma refuses to sell. After Grandma disappears following Santa's sleigh crashing, Mel discovered a letter revealing Grandma's whereabouts, but decided to hide it for about one year to keep her family and the rest of the town in the dark about it. She also tries a scheme to force the sale of Grandma's store by tricking Grandpa into signing over his power of attorney to her, but Jake tries to stop her.
Mel hates the spirit of Christmas and is the cause of Santa's arrest when she frames him for Grandma's disappearance. She has an unscrupulous attorney named I.M. Slime, who assists her in her scheme to kidnap Grandma after she returns and to frame Santa for the crime and sue him to get all his money. She is eventually found out by Jake when he finds the missing letter in order to prove Santa's innocence and, after she is forced to confess her actions during Santa's trial when she is confronted with the evidence against her, she is arrested and sent to prison while Santa is cleared by the judge.
