Mom takes Tiny, Buddy, and Don on a super secret daytrip to Qianzhousaurus Pond, where they meet Quentin Qianzhousaurus – a Tyrannosaur with similar features to Buddy, except for one major thing – Quentin has a long, thin snout covered in tiny horns! The kids think that Quentin’s long snout gives him a super smelling sense, but after a series of tests, they realize that he and Buddy have the same sniffing power. Can Quentin and Buddy’s super sniffers solve the mystery of Mom’s secret daytrip?
