It's a sunny day near the beach. Ash, Misty, and Brock enter their house and they plan to spend their Christmas time in it. Ash tells Pikachu that he is in charge when they go to pick up a Christmas cake. When they leave Togepi begins to walk down the hallway. It comes across a door and goes inside it. The other Pokémon follow Togepi and they see the big Christmas tree. Squirtle sees another room and all of the other Pokémon go inside it. The room is filled with party hats and food. They pick up the party hats and they put them on their heads. Psyduck tries to put the party hat on his head but it ends up falling on its tail.
Pikachu and Togepi go back to the Christmas tree again. They look in the ornaments and to see their reflection. Pikachu makes some funny faces when looking at the ornament. Bulbasaur picks up a Christmas cookie from the table. Squirtle begins to pull on the string that's attached to his party hat. Before Bulbasaur can eat the cookie, the party hat pops. Bulbasaur jumps which makes the cookie fly in the air and land in Squirtle's mouth. Bulbasaur gets mad at Squirtle and it starts to chase Squirtle. Vulpix has his head in the stocking. It's taking out all sorts of things from the stocking such as candy and other goodies. Then Vulpix gets its head stuck in the stocking and it can't get it out. Vulpix starts to walk but runs right into a wall.
Meanwhile, Psyduck stares at a Pokémon Cider bottle. Psyduck picks up the bottle and tries to open it with its mouth. Since Psyduck can't open it, it happily shakes the bottle. Bulbasaur is still chasing Squirtle. Now they are in the room with Pikachu and Togepi. Bulbasaur uses vine Whip to get a hold of Squirtle. However, Squirtle runs behind the tree and the vines start to pull the tree down. Pikachu manages to push the tree back up to its normal position. Vulpix flies out of nowhere and lands on the top of the tree. The stocking falls off of Vulpix's head and Pikachu pushes the tree back up again. Still getting chased from Bulbasaur, Squirtle runs in the back of the tree again. It trips over the string of Christmas lights and all of the ornaments start to fall off the tree. The tree starts to fall again and Pikachu is pushing really hard to get it back up. Suddenly, the bottle cork to the Pokémon Cider that Psyduck was holding pops off. It bounces off the walls and it hits Pikachu right in the head. Pikachu falls down with the Christmas tree right on top of it.
Pikachu crawls out of the mess and Squirtle and Bulbasaur laugh at Pikachu. Pikachu gets up and is really mad now. It hurls a Thundershock at them but the attack manages to destroy the lights. Now it's pitch black in the house. Pikachu finds a box and it opens the box. In the box is a Christmas tree with flashing lights and playing some soft music. It lights up the room and everyone stares at it for a while. Suddenly, it stops working and everyone is now sad. Pikachu tells the other Pokémon to help pull the Christmas tree back up.
Ash, Misty, and Brock get back from shopping. They find it to be really dark in the house. When they open the door, the Christmas tree lights go on. Pikachu is supplying the electricity to keep the lights on. Everyone is very happy and they have some good Christmas fun together.
It's sunny outside and everything is covered with snow. Ash, Misty, and Brock walk in their cabin. They call out for the Pokémon. Ash tells Pikachu that they are going shopping and that he is in charge for the time being. When the door closes, the Pokémon hop on a table to see their trainers leave. Chikorita jumps on one of the chairs. Soon, the other Pokémon comes running down and they knock Chikorita off the chair. Squirtle breathes on the window and puts his face mark on it. Pikachu does the same thing. All of the Pokémon are having fun except for Chikorita. Pikachu runs to Chikorita asking it if it wants to play but Chikorita says no. Pikachu walks towards Chikorita a bit more and then Chikorita knocks a shoe into the air which lands on Togepi. Then Togepi starts to cry. Everyone tries to calm it down but nothing seems to work. Then Vulpix sticks out its tail and Togepi and it stops crying.
Chikorita runs outside and all of the other Pokémon follow it. Chikorita continues running. It sees an icicle and runs right into it. Everyone laughs at Chikorita. They start to bang on the icicles to make some sounds. Chikorita gets an idea. It shoots out a leaf which cuts one of the icicles. The icicle almost hits Squirtle and Chikorita laughs. It does the same thing. The Pokémon manage to avoid the hit except for Geodude. But Geodude doesn't feel anything because it's a rock. Chikorita runs away again with the Pokémon chasing it.
An ice rink is ahead and Chikorita runs right into it and it starts to slide. Pikachu stops and all of the other Pokémon run right into Pikachu. They fall down the stairs and Pikachu slides on the rink as well. Pikachu bumps right into Chikorita but Chikorita uses its leaf on its head to stop them. Chikorita just walks away and sticks out its tongue at Pikachu. The other Pokémon begin to slide on the rink. Pikachu takes Togepi and it pushes it gently. Then Squirtle gets into its shell and Bulbasaur pushes it. Squirtle hits Psyduck, Poliwag, Heracross, Vulpix, and Geodude. But Squirtle stops and hurts its head when it hits Geodude.
Meowth appears on the top of the stairs. Meowth decides to give it a try too. It takes a step on the rink and it already starts to slide out of control. Poliwag and Chikorita go in front of Meowth and they make the ice as slippery and slick as possible. Meowth slides even faster and bumps into a tree and a bunch of snow falls down on him. Everyone laughs at Meowth. Meowth sees Vulpix making the ice very slippery for Bulbasaur. Meowth decides to help Vulpix and Bulbasaur slides even faster and bumps into a tree as well. Meowth laughs at Bulbasaur. Bulbasaur gets mad and it uses its vines to grab Meowth and spins him across the rink. Meowth bumps into some of the Pokémon. Squirtle and Meowth spin the same way. Squirtle knocks Meowth off the rink and sends Meowth blasting off again.
Everyone is happy and Chikorita rejoins the group. Everyone does some more sliding when Ash, Misty, and Brock call the Pokémon over. Everyone hops off the rink except for Psyduck which falls on the edge of the rink.
