Some people think that museums are boring places full of glass cases, dust and stuff no-one cares about: wrong! In a hidden headquarters below the exhibits there's a gang ready to handle dangerous, spooky or just plain weird problems: the Museum Mystery Squad.

Techie-genius Nabster, mile-a-minute Kennedy, and sharp-eyed Laurie (along with Colin the hamster!) tackle the surprising conundrums happening at the museum. From moving pre-historic creatures and secret Egyptian codes to missing treasure and strange messages from the past, there's no brain-twisting, totally improbable puzzle the Squad can't solve.

There's nothing deader than a mammoth -- not just dead but completely extinct. So how can it be moving at night?

In the Case of the Moving Mammoth, the Squad investigate the museum's new star exhibit, on loan from Tyrone O'Saurus, ringmaster of the travelling Dinosaur Circus. There must be a reasonable explanation for a shifting stuffed prefistoric animal. Can they sift through the clues and unravel the puzzle before the museum faces a mammoth-sized problem?
