Carving a watermelon into a big ol’ dinosaur head is—pardon the pun—a no-brainer. A quick online search for “watermelon dinosaur” results in myriad images that offer an easy approach: Take a big angled slice out of the lower half of the melon and you’ve got yourself a gaping maw. Cut honeydew, cantaloupe, or pineapple into small triangles and affix them to the dinosaur’s upper and lower jaws with toothpicks. Voilá, you’ve got teeth! As you would with a jack-o’-lantern, carve out nostrils and maybe some eyes, then grab those toothpicks again and affix grape or blueberry eyeballs. Fill the dinosaur’s mouth with fruits such as berries, grapes, and cherries, or scatter them on a platter with your T-Rex masterpiece in the middle.

This dino-party essential can be approached in any number of ways, depending on your level of ambition. If deviled eggs are your specialty, by all means go this route. (Turn them into dinosaur eyes with slices of strategically placed pitted olives.) For less work, provide art supplies, from stickers to nontoxic markers to egg dye and stencils, with which to decorate hard-boiled eggs. Create a raffia nest within a large shallow bowl for the eggs—or hide them and have your little explorers go on an archeological expedition. Learn how to make the perfect hard-boiled egg here.
