Returning from the camping trip, the gang suddenly realises that they are well and truly lost in Beanotown forest. They find themselves in the Lost World – the place where everything goes when it gets lost.
There, among missing javelins and lost chew toys, sits the empty nest of a Gnashersaurus Rex! The towering dinosaur sees the gang, and steals Gnasher, mistaking him for a baby Rex who hatched from an egg!
The only way to get him back is for the gang to get un-lost, find the missing Gnashersaurus egg, and return to the lost world to retrieve what they’ve lost. Got it?
