Pikachu's Winter Vacation (Christmas Night and Kanga Games) - S1.E1

Christmas Night

Ash and the gang are spending the holidays in a house by the sea, and they leave their Pokémon to look after things while they run errands. As the Pokémon explore the house, they admire all the holiday trimmings, including party hats, delicious treats, and a Christmas tree. Bulbasaur and Squirtle get into a fight over the treats, while Vulpix gets stuck in a stocking. Pikachu tries to keep everyone from wrecking the house, but it's too much for one Pokémon.

Kanga Games

Ash and his friends are staying in a wintry mountain region, which means lots of snow for all their Pokémon to play with. Togepi wanders into the woods and encounters a friendly Kangaskhan and its baby, who's feeling shy. But the baby Kangaskhan grows curious when it sees all the other Pokémon playing and throwing snowballs at each other. Soon it's running around and throwing snowballs with the best of them!
