this was my second attempt at sculpting. still have problems with crumbs. covered with buttercream, then fondant and painted with food color (wish i had an airbrush, would have looked smoother). fins are cardboard covered with fondant. mouth is cardboard, covered with fruit roll up, then jammed in a slit i made at the front of the cake. teeth are piped icing. lemon cake inside, with red food color made it a salmon color when we cut it open. my daughter's boyfriend was thrilled with this for his birthday, as he has a tatoo of a shark on his ribs.
