Way to spruce up a tray of veggies! First, cut up your veggie slices - you can use carrots, cucumbers, tomatoes, or any other vegetable of your choice that pairs well with hummus. Cut a small portion off the bottom of a bell pepper and empty the insides, being careful to keep the bell pepper intact. Once the insides are empty, slice the piece you cut off into 6 long strips and save them for later - these will be the tentacles.

Place a bowl of hummus in the middle of a platter, and surround it with the sliced veggies. Place the bell pepper on top of the hummus and add a pair of edible googly eyes to the top. Add the 6 remaining slices to the sides of the bell pepper and your octopus veggie tray is ready for snacking!

Make sure to fill the pitchers with ice to keep your splash-tastic drinks cool.

20. Watermelon Shark

Cut a third of the watermelon off and place it on its flat side. Using a large knife, cut out the shark's jaw and its bottom and top teeth.

Once the inside of the shark head is emptied, place it on a round tray and fill it up with the slices you cut out. To finish off your jaw-dropping arrangement, secure two blueberries in place of the eyes using toothpicks.

21. Banana Dolphins

These banana dolphins are so cute you won't want to eat them! Cut the bottom ends of the bananas and place them standing upright.

Use a black marker to dot the eyes on the banana.
