When Saara's fear of heights puts her at risk of failing her swim test, Dana enlists the help of a Deinosuchus, Spinosaurus, and Pterodactylus to show Saara there are different ways to conquer her fear and get into the water. Dana is studying the hunting techniques of the Microraptor when she finds a mouse in the kitchen. Things gets complicated when the Microraptor accidentally gets inside and begins to hunt the very mouse Dana's trying to save.
