The tour bus is acting erratically and Ami and Yumi go inside to find out what is wrong. They find out that the man who sold them the bus had moved into its carburetor. The girls get him out and the bus is fine.

Yumi is mistaken for a secret agent and must handle the real Agent Y's job.

Ami must fight the Black Knight to see who will defend Kazalot.

Ami joins Kaz's football team, not knowing that this is a dangerous sport. Kaz tells the security guard not to let Yumi in, because he does not want her to stop Amy playing. Yumi dresses like a cheerleader and gets in. Seeing that Ami doesn't have a chance against the other players, Yumi helps her without Ami realising it.

When Yumi is struck by lightning, she is sent to an alternate universe where everyone is evil. Meanwhile, Yumi's evil counterpart is put in Yumi's place and wreaks havoc.

Ami's cell phone overuse causes Kaz to take her cell phone away, leaving Ami to find alternate methods to communicate with other people.
