Fin is a dinosaur unlike any other - teased for his 'spindly little legs, bony tail and feeble fluffy arms'. But despite his odd appearance, when a gang of four big, bullying dinosaurs chase him into the woods, Fin outwits them one by one. All except the meanest, fiercest dinosaur of all who follows him right to the top of the mountain, where Fin takes a giant leap of faith and discovers ...he can fly!
