The Treetop family have invented a time machine and used it to travel back in time to the land of dinosaurs. The Treetop twins go on an adventure in search of a pet dinosaur. They find a mouse-looking Megazostrodon which seems perfect, but when they try to catch it, it runs all the way up the tail of a huge Massospondylus. Will do twins manage to get out of danger this time?
