"Arlo is a brave, hard-working farm boy who dreams of doing more than brushing the unibrows of his unicows. Julia's a plucky adventurer who is tired of having no one to talk to but her onesie-wearing father. With nothing in common but embarrassing dads, Arlo and Julia find themselves on a quest to save the land of Ticklebrook from eternal grumpiness and disgusting lemonade. All they have to do is find an invisible island, face a freaky foe and bring home a Super Epic Dragon treasure!"--
