Watermelon Shark

This idea comes from the Watermelon Promotion Board, and Sun Scholars has a photo tutorial on how to make it.
Just in case the links break in the future, I have included the instructions here.
National Watermelon Day is August 3rd.

1 oblong watermelon
Large knife
Smaller utility knife
Large spoon
Paring knife or the tip of a vegetable peeler
2 blueberries
Toothpicks or wooden skewers

Swedish fish candies

Wash and dry the watermelon. Cut off 1/3 of the watermelon at a diagonal angle.

Stand the remaining 2/3 upright on your work surface and cut a line for the mouth and eye sockets. Make sure here that you are adding about an inch or so for the teeth you will be cutting out of the rind. Cut out the mouth. Make sure you save the mouth wedge for the fin.

Next, with a small knife, carefully score around your shark mouth, about a 1/2 inch up and only about 2-3 millimeters deep. This will help you to peal off the rind down to your cut so you can begin to form the teeth. carefully cut away the green rind down to your score lines around the mouth, and set it aside to use later.

Use a large spoon to scoop out the watermelon flesh, leaving 3" intact at the base.

Cut out triangles for the teeth, using a smaller utility knife.

Use small knife and a melon baller to cut into the rind, being careful not to cut all the way through, to make an eye socket and the lines for the gills behind the mouth. Use a paring knife to trim the green area around the eyes. Break a toothpick in half and used that to attach a blueberry to the center of each eye.

Take the wedge you cut to form the shark mouth to make your fin. Cut wedge into triangles to make the fins. Remove the watermelon from the other side. You might need to cut a bit of a curve on the bottom side to have it fit.

Fill the mouth with triangle shapes of watermelon, accented with Swedish fish. Now you have a shark!
