Pretty simple steps
Step 1: Body Parts
First you could make your own rice crispy treats or you can use the ones you use in a store.the diets thing you do is you have to mold the RC into shape to what ever you want make sure they look right together.
Step 2: Combining
Now you take all the part and combined them with tooth pick but don't use the whole tooth pick only use the tip. Once you have that done make sure there in the place you want.
Step 3: Ta Da
Here's the hardest part,take your fondant and roll it out with a little powdered sugar till its really thin or thick you can pick. Now lay it over the RC TREATS cut it and mold it to the animal you can make this with and animal you really want. This creation is more for decoration than food .HAVE FUN
