1 oblong seeded watermelon
2 red grapes, peeled
Your favorite fruits for fruit salad, such as pineapple, cantaloupe and honeydew, chopped or cut into fish shapes
On a cutting board, cut off the bottom 1/4-1/3 (depending on size) of the watermelon on an angle. Stand the watermelon up on the cut surface, making sure it is steady. Find the midpoint of the watermelon at the top and draw a line marking where the top of the mouth will be. Mark another line below it, to make the bottom of the mouth opening. Using a paring knife, cut along the lines and pull out the mouth piece. Reserve.
Scoop out all flesh out of the watermelon, leaving a gap at the bottom, so that the fruit salad doesnt fall out.
One inch above the top and bottom of the mouth, score a line and scrape off all green skin to show the white rind. Carve small triangles into the top and bottom of the mouth to form shark teeth.
From reserved mouth piece or from bottom, cut out a triangle and attach it to the back of the shark to make a fin with 2 toothpicks. Stick a toothpick in the grape and put it on both sides of the sharks head to make eyes.
Fill with fruit and serve.
