All buttercream icing; all edible with the exception of the toothpicks obviously! Raisnettes for the rocks; small pretzels; pretzel rods; sugar cones; graham crackers for the tent....I had soooo much making this cake! I got my inspiration from a photo on here! So thanks to whoever did this cake first! The little girl I made this for ran up to me and hugged me and thanked me saying " I love it"..
