If you haven't checked out Creative Kid Snacks before, they have some fabulous ideas to make food fun. Mine are not quite as good as the original design but the kids loved them all the same ;)
You will need:
Slice a chunk of banana, keeping it as straight as you can. Cut a marshmallow in half and place one part sticky side down on a plate. Put the banana chunk on top. Add the other half of the marshmallow on top of the banana and put a strawberry on top. (I used cocktail sticks to hold them up if they wobbled, and just removed these after the kids had looked at them and before they started eating!)
Melt the choc chips in the microwave, and dot on two eyes and a nose. Add a tiny strawberry piece for the nose on top of the chocolate dot.
