Alanna met Ash and his friends outside of the Trick House. Like them, she wanted to enter the Trick House contest in order to win the one-year supply of Pokéblocks. She was accompanied by her Whismur. Alanna seemed to be a fan of The King of Tricks. While May thought he was crazy she believed he was eccentric.

During the maze portion of the Trick House, Alanna got separated from her Whismur. Team Rocket wasted no time to use this opportunity to steal Whismur and give it to the boss. Unfortunately they couldn't exactly find their way out of the maze.

Soon the group gets out of the maze the same time Team Rocket does. Alanna sees that they have her Whismur. But because Team Rocket were wearing disguises, she thinks that they rescued her Whismur.

Alanna sticks with Ash and the gang through the rest of the Trick House. However they kept getting sabotaged by Team Rocket. They eventually attempt to steal Whismur and Pikachu again. This time Ash and Alanna battled them and send Team Rocket blasting off. Unfortunately none of them reach the end first. A boy named Ivan was the winner.

Alanna's Whismur develops a friendship with the recurring Jigglypuff, being that it is the only one that does not fall asleep during its song due to its ability. By the end of the episode, Whismur was tired from all the battling and went to sleep. Jigglypuff believed that it fell asleep because of its song and gets mad at it.
