Peel the carrots.
Chop them into discs.
Place two small bowls of hummus for eyes on a platter.
Use the round cutter to make cucumber peel eyes. Top with a bit of mozzarella for the highlights.
Arrange the carrot discs around the bowls and make a slight indent between the eyes so it resembles a pumpkin.
Place some cucumber slices for the stem.
Make the mouth using a long strip of mozzarella or cucumber peel.
Serve.
