Instructions
Position yourself right in front of the watermelon.
Press the "R1" button when you are ready to pick up a watermelon. The character should grab the watermelon.
Hold the "R1" button until you have enough strength to throw it. The watermelons are heavy, so the further you have to throw the watermelon, the longer you hold down the "R1" button. To throw the melon, just release the "R1" button.
