When Bully and his friends spot what they think is a shooting star, heading straight for their forest, they are intrigued. So intrigued that they set off to find it - wherever it has landed. But what they find is not a star - it's an alien called Zooble. Zooble can't remember where he has come from, or where he was headed - all he knows is that his spaceship has crashlanded in the middle of nowhere, and he is anxious to fix it and be on his way. The dinosaurs lend a hand, and finally Zooble's ship is ready for departure. Bully and his chums are sad - they have grown rather fond of Zooble . But before they know it, Zooble has returned - he has remembered where he was headed and it was right here with his friends the dinosaurs - Zooble was looking for home . . .
