I would first like to start by saying, most any shape can be made out of a Crispy-Rice treats recipe. The one I use for the Hedgehogs is the basic one you probably have filed away, or it is on the back of your cereal box. You'll need to make 1 recipe for this project.
After combining all ingredients, let your treat mix cool for a couple of minutes in the pot. You'll be handling these with your bare hands and you don't want hot marshmallow to stick to your fingers.
All the recipes I've ever read about shaping treats says to butter your hands before shaping. This does not work for me. I use a bowl of cool water. Lightly dip your hands in water before you pull a lump of treat mix out of the pot for shaping. Nary a crumb will stick to you. Continue to dip your hands in water if sticking occurs. When you are shaping try to form a teardrop with one slightly pointed end.
For dipping I use 1 cup of chocolate chips and 2 teaspoons shortening. Microwave the ingredients in a bowl at 30 second intervals until smooth and runny. Spoon over the rounded end of the treat, avoiding a 1-2" space at the pointed end for the Hedgehog's head. (see pictures below)
You'll need to get some chocolate sprinkles. These are relatively inexpensive and make the perfect spiny look for the hedgehog's coat. I found these at the Amish market, but they do carry them at most all grocery stores in the baking section.
I piped some icing for the eyes and nose on these little fellas. I also added a fondant flower for the Mama Hedgehog since I had extra from a previous project. You could also use chocolate chips for the eyes and a red-hots candy for the nose. EASY!
