First open scratch and delete the cat. Then go to File and select the animals folder, scroll down and then select fish 4. Then go to looks and drag a "change color effect by 25" block. Next, go to control and drag a "when space key is pressed" and snap it onto the other block. Now, whenever you press space, the fish will change color like a rainbow. -End of tutorial one- Feel free to play around with this and try things out. Nothing beats experience.
