Episode Title:Teddygozilla.Episode Description:Milly and Tamiya are doing a report on the school prom. They try to interview Sissi, who was prom queen last year, but she turns them down and makes fun of them for their age. Milly tries to ask Ulrich out, and he turns her down because he's going to the dance with Yumi. Upset, Milly storms off. In her room, she tells Tamiya that she hates everyone, with X.A.N.A. listening from her computer. When Milly tells her teddy bear that she wishes she were bigger and leaves it in the garden shed, X.A.N.A. possesses it and uses it to attack those who make fun of her. It then increases the teddy bear's size to roughly two stories and sets it on the town. Since Ulrich is to protect the school and warn Yumi, it is up to Odd to go to Lyoko and help Aelita deactivate the tower and protect the rest of the town from the rampaging teddy bear. After a return to the past, Milly asks Ulrich to the dance again, and Ulrich complies, embarrassing Sissi.
