A.N.T. Farm - Season 1 Episode 3 -

Annoyed with China's friend Olive (who shares a locker next to him), Cameron convinces Olive that a ghost inhabits her locker, which causes her to become locker mates with China; when this proves to be too much for China to bear, she tries to convince Olive that there is no ghost in her own locker. Meanwhile, Fletcher is asked by Principal Skidmore to paint a portrait of her, and gets more than he bargained for.
