Using a paring knife and working at an angle, cut around one end of an oval watermelon to create a lid, then scoop out the fruit with a metal spoon. With a clean screwdriver, poke a hole about a third of the way up the watermelon, then use a paring knife to make it slightly smaller than your spigot (Stainless Works Beverage Spigot, $13.95; Amazon.com). Gently screw in the spigot so it fits snugly. Handwrite " Enjoy" above the spigot in permanent marker, then use a linoleum cutter to trace the letters and etch away the skin. Fill with watermelon limeade, then replace the lid and position on a stand.
Halve a small red or lady apple. Cut a slit in the rounded side, then poke holes and insert peppercorn spots. Use half a toothpick to attach a blackberry gummy candy for the head, then push in apple stems for antennae.
For the dolphins Slice the stem of a banana, spritz with lemon juice (to keep from browning) and place a small raspberry inside. Poke holes and insert peppercorn eyes, then attach grapefruit gummy candies with toothpicks for fins and a tail, as shown. Position the dolphin inside or next to the wave bowl.
The Tortoise and The Frog
For the frog With a paring knife, cut a mouth into a round watermelon. From the cutout, carve a watermelon tongue and use a melon baller and the knife to make eyes from the rind; attach using toothpicks. Use a screwdriver to poke nostrils. From a second watermelon, use a large serrated knife to cut off the end, then cut it in half to create the two hind legs. Next, cut two 1-in.-thick wedges for the front legs. Using a paring knife, cut four feet from the rind. Secure, as shown, with toothpicks. When ready to serve, cut into pieces.
