Chocolate cake covered with fondant, seaweed done with royal icing, decorations with smarties/mnms and fondant. The pineapple was choc cake cooked in a coffee mug, covered with fondant and stripes painted with brown royal icing. I have never tried cooking cake in a drinking mug before but it works! Bubbles are made from white choc (tinted blue) on wire. Treasure chest is a mini Mars bar with yellow smarties in it. Spongebob is a bought candle.
