This Metamorph egg amazingly transforms into a pre-historic creature. Twisting open the egg reveals a collection of dinosaur body parts; once simply slotted into the correct holes on the egg's surface, the puzzle turns into a nicely detailed model dinosaur.

Each design comes with an information sheet providing statistics about the species of dinosaur, alongside facts to share with friends in the playground. Some of the assembled models appear more anatomically correct than others, but all are clever self-contained puzzles and playthings - and even the obese T-Rex with stubby legs has lots of charm.
