T-Rex and Imprint

Andy travels back 65 million years to North America in the time of Tyrannosaurus rex. His mission is to get a clay imprint of the skin of a T. rex. Since T. rex was one of the largest and fiercest meat eaters on the planet, he has to wait for one to fall asleep, but with adorable T. rex babies to look after, the mother T. rex is anything but tired. Will Andy succeed and make it back to the museum in time?
