Pokemon: Pikachu no Fuyuyasumi (2000)

Pikachu and the other Pokémon spend their winter break playing in the snow, but a day of games quickly becomes chaotic when Chikorita wanders off and the group discovers an ice rink full of new ways to compete and make trouble.

Later, they encounter Santa Claus and a sick Stantler unable to continue its work. To save the night, Pikachu and its friends search the snowy mountains for a special berry that can cure Stantler before Christmas is ruined.
