Hatty works as the head of the Dinosaur Gallery at the National Museum with Andy. After part of an exhibit is damaged, Andy disappears and later returns with a replacement piece, leaving Hatty confused. She doesn't realise that Andy had traveled back in time to a prehistoric era using the Old Museum Clock to find a replacement piece. (Andy's Dinosaur Adventures)

She did not return for Andy's Prehistoric Adventures. It was suggested that she’s gone off on a trip around the world to look for more fossils – or maybe she’s gone to work at Jurassic World! [1]
