T-Rex and Roar

S1, E19: Andy travels back 65 million years to the time of Tyrannosaurus rex - Andy's favourite dinosaur of all time. It also had a pretty impressive roar which Hatty has simulated in the museum using the trumpet of an elephant and the bark of a dog. When the CD of the sound effect gets damaged moments before the museum opens, Andy vows to fix the problem. His mission is to track down a T-Rex and record its massive roar - but that will mean getting up close and personal with one of the biggest known meat eaters on the planet. Will he succeed, and will he make it back to the museum in time?
