Lilian Bouregard was born to Misty and Ash Ketchum. Ash decided to leave Misty for another woman, so Misty changed their last names back to Bouregard.
Lilian had a fairly standard childhood until she met Billy and Ivy, and close rivalry formed between the three.
When Lilian turned 10, she chose Shinx (which she named Mint) as her first Pokemon, and they set out to get all the gym badges.
Mint was found by Professor Aiki on a stormy night on the doorstep of the Laboratory, said to have been horribly injured.
Later, Lilian chooses Mint to be her first Pokemon. Mint seemed very pleased to be chosen by Lilian.
Mint is a willing fighter and defender of her friend and trainer, but very mysterious and knowing in nature.
Toffee grew ill with Pokerus after drinking from a nearby pond. A wild Ratata targeted and attacked him, but Lilian stopped it and took the Deerling to a nearby Pokemon Center.
It was there that Toffee saw what he'd always wanted: A friend. He joined Lilian's party.

Unlike many of his species, Toffee enjoys having a partner, travel. He doesn't like to stay at Deerling Meadow where he came from, where Deerling come to rejoice and choose mates, rather, he likes to hang out with Mint and sightsee.
