This Vanillite is an ice-type Pokémon owned by Teaque.
While Teaque fought in the Marine Tournament, Vanillite went into Mrs. Ripple's room, through the air shaft, and used Ice Beam to form a key to unlock the chest. Vanillite took the gem and went off, but the key melted and was left for Cilan as a clue. Teaque was discovered as the thief and sent Vanillite to use Blizzard, but was stopped by Tedesco's Growlithe.
