The Pteranodon Family decides to take a little vacation and swap nests with Larry’s friends: a family of pterosaurs (Nemicolopterus, to be exact). But when the Pteranodon Family arrives at the Nemicolopterus nest, they realize that the Nemicolopterus Family is MUCH smaller than them, so everything is smaller: the Pteranodon Family doesn’t even fit in their nest! Can the family make do, try something new, and still have a good time?
