Let's Rock! (Quel rythme !)

Harry's sister Sam has created a band with her friends and Harry wants to be in it. Thing is that Harry seems to be playing out of tune and so Sam feels he's not ready for a band. Harry searches for places to practice, but can't seem to find an ideal location, until he decides to go play in Dino World. Harry and his dinosaurs find a stage in Dino World and decide to make their own instruments. They have a great time playing, but Pterence doesn't seem to be playing at the same speed as everyone else. When the rest of the dinosaurs insult his play, Pterence himself leaves the band in search of somewhere else to play.
