Click 1 and 2 to switch dragons, and click the c button to change colors. Click f, v, g, and b to switch backgrounds. You unlock the third dragon once you catch 15 prey, and can use it by clicking 3. You unlock the fourth dragon when you catch 30 prey, and can use it by clicking 4. Also, if you for some reason can not collect the Diamonds, just click the green flag again.
Kestrelpaw is good at coding!;)
