It's Miley's birthday! Robbie is trying to find something special for his little girl. Miley tells Lilly to steer Robbie to the right clothes, but it still doesn't work. Now Miley has to wear this tacky sweater to her birthday party. Meanwhile, Jackson is trying really hard to give Miley a birthday cake and not mess things up (again).

Miley, Lilly, and Oliver are just itching to get revenge on bratty Amber & Ashley during a class camping trip, even though Robbie told Miley not sink to their level. When Miley and her friends give the girls their comeuppance, she thinks that they got away with it, but she finds herself with a whole new itch to scratch as Hannah Montana. Meanwhile, Jackson and Robbie try to rid themselves of a mouse with a surprising talent.
