It’s a hot summer and Charlie creates a tasty fizzy drink for the dinosaurs to enjoy and to keep them cool. But there is an unexpected side-effect: very smelly dinoburps. To start with everyone finds it quite amusing, but the burping continues, even when the dinosaurs stop drinking the pop. No one can get any sleep and there’s a horrible smelly fog lingering over Sabreton! It’s up to Charlie to make a dangerous journey through the jungle, across the sea and to a volcano to get the remedy. But, to make matters worse for him, he has to do it with a girl!
