Click on the watermelon. Then it will break. Click on one of the halves (not the space in the middle, or else nothing will happen because it's the background) and it will go back to the original, full watermelon. That's it!
I did not spend much time on this at all. I made this project because I felt bored and had nothing else to do. It's probably really boring for you, but click it if you want to. Okay. Bye!
