This was not a birthday cake, but it was one we made just for fun. Aunt Vickie baked two round, 9-inch cakes with store-bought yellow cake mix. One cake was used whole to make the body and the other cake was cut to make the tail and the fins. Aunt Vickie and cousin Brad decorated it with M&Ms. The eye was a marshmallow wth a brown M&M on it. The mouth was two red Dum Dums.
Thanks for all your help Aunt Vickie and cousin Brad!
