'Planet Earth is just amazing,' said Flarp. 'Mostly, it's a planet of beetles, but if you look closely there's so much else going on, too.' Shhh! It's midnight at the Museum of Earth Animals, where a class of Martian children are on a special sleepover school trip to learn about all the strange and fascinating creatures of Earth. They're all snoozing peacefully when ... CRASH! Something is causing chaos in the galleries and it's up to Lolo and Flarp to figure out WHO or WHAT it is. Is it a burglar? A monster? A dinosaur? Follow our Martian friends as they explore the museum halls at night, finding out lots of fascinating animal facts along the way. Featuring funny text by zoologist Jules Howard, magnificent illustrations by Matt Hunt and fold-out pages with lots to spot, this is a book kids will reach for it again and again.
