Double click the green flag! Then hover your mouse over Scratch Cat............
When the Cat touches the fish, the fish moves and does an effect. When the fish touches the hippo, the hippo moves and does an effect. When the hippo or Cat touches the dinosaur, the dinosaur moves and does an effect. When the dinosaur touches the dog, the dog moves and does an effect. By the way this goes on forever, so better not watch till the end :P
