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. Has someone been taking money from the museum's donations at night? Why are there coins all over the floor? In the Case of the Curious Coins the Squad enlists the help of a few metallic friends - robots from a new futuristic exhibition. These super-cool robots might be able to build furniture, cook up a feast and send messages, but can they spy on a thief?
