Mandy

Mandy's History

When Mandy was a baby, she was shown to have never smiled; she was even visibly unhappy in her mother’s womb. When she does smile, it throws off the natural order of the universe as seen in one episode, "My Fair Mandy". However, this did not apply in some earlier episodes, where she smiled only to her friends Billy and Grim. However, she had to smile in front of everybody in the school auditorium when she sang Over the Rainbow as part of a pageant.

In the episode The Problem with Billy, it was shown that she first met her best friend Billy at an early age, when Billy had repeatedly rung her doorbell until she was annoyed enough to answer. Later, Billy stole her feeding bottle, put it in his mouth and began flushing it like a toilet. When she did, he immediately pointed out that she had no nose and shoved an ice cream cone into her face after she had asked him if he was "some kinda idiot?". She punched him, called him a creep, and slammed the door in his face. He simply giggled in response to this, telling "she digs me", thinking that she liked him.

Years later, she and Billy had met Grim on the day of the tenth birthday of Billy’s pet hamster, Mr. Snuggles. Grim had appeared to reap the soul of the hamster as it was time for the hamster “to kick the bucket” as Mandy had said earlier in the episode, but neither the hamster nor the duo would give in. So, they made a bet. If Grim beat them in a game of limbo, he could have Mr. Snuggles and Billy, but if the kids won Grim had to be their best friend forever. However, the kids won after Mandy cheated in the limbo contest and Grim has been stuck with them since. In the episode Sickly Sweet, Mandy turns into a monster with the combination of Hippopotamus, Alligator, Bear, and Iguana by "The Mask of Beast" for her cynical attitude with Billy and Grim.
