Anxious to leave for Driftveil City again, Ash and co. decide to take in some culture with the Pokémon musical. They meet Toby, a young trainer and his Maractus trio: Marra, Racca and Tussy. However, Tussy was struggling to overcome with its fear of heights as it was trying to perform an "Over the Rainbow" technique before the performance competition and the audition in Nimbasa City for the Pokémon Musical. Can Tussy get over its fear of heights by showtime? Yes.
This is the first episode to feature an official Triple Battle.
Like the character name Cowardly Lion from "The Wizard of Oz", the only reason why Tussy can't get over its fear because she's confusing her wisdom.
