Harry and His Bucket Full of Dinosaurs (2005)

Season 2: Episode 37

Harry’s got the giggles and they’re contagious! Before long, all the Dinos are in stitches too and are surprised when they hear a voice telling them to stop laughing. They soon discover that the voice belongs to the Fairy Princess in Dino World and they jump into the bucket to investigate further. When they arrive, a court jester informs them that the Princess has lost her smile and so has banned all things funny. As a result, Harry and the Dinos launch a campaign where they try every funny trick in the book to try and make the Princess laugh again. Alas, it’s all to no avail as the Princess remains stony-faced and convinced that the Royal Smile is never to return…Will they ever manage to find her smile again?
