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. Before long, the Christmas tree is toppled and the lights have been blown out!
Now Pikachu needs everybody's help to put the house back together. The Pokémon help each other right the Christmas tree and clean up the mess they made; when Ash, Misty, and Brock return, the Christmas tree is lit—even if it's being powered by Pikachu's electricity! Trainers and Pokémon all wish each other happy holidays and enjoy their own party with friends.
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! Then Togepi and the baby Kangaskhan find a toy sled and take it for a ride, which inspires all the other Pokémon to try sledding. One problem: there's a giant lake directly in their path!
Mama Kangaskhan leaps in to stop everyone from falling into the water, and it turns out that Kangaskhan also makes a pretty good playground for small Pokémon. Everyone has lots of fun playing, but after a fun day in the snow, it's time for the two Kangaskhan say goodbye. Then Ash and his friends come looking for their Pokémon, who are especially happy to see them. There's nothing like the caring bond between a mother and its baby, or a Trainer and their Pokémon!
