Harry is curious to know what a ‘quest’ is after he sees Sam reading a book about Jason and the Quest for the Golden Fleece. While Mom is explaining, Nana mentions that Mom’s birthday is coming up and Harry and the Dinos decide to go to Dino World to embark on a quest of their own to find the perfect birthday gift. After jumping through the bucket, Harry and the gang discover an Ancient Greek rowing ship with Medea as the figurehead. By a stroke of luck, she has a whole chest full of quests for them to choose from, including one to find ‘the most amazing necklace ever’ - what could be better for Mom’s birthday?! Medea invites them all aboard and they set off on a treasure hunt to follow the clues that will lead them to their precious necklace. But with rivers and lakes to cross and a dancing giant cat to help en route, it isn’t going to be easy!
