Hawaiian Anniversary cake

Pineapple cake with vanilla buttercream frosting. I made the sand out of equal parts of graham cracker and brown sugar. I used the Wilton method for making the palm trees. They didn't make it to the party, one tree only had three leaves and the other had one leaf. Not sure if a longer drying time would've helped. I used cookie sticks for the palm tree trunks and 'fencing' around the cake. All the other little decorations were out of MMF, except for the umbrellas, of course. For the water, I used piping gel colored blue, put some frosting tinted light green underneath. I used Carolyn's hibiscus cake from Terrisa as a guide in making the water. Thanks Terrisa!
