This is a cake that I did for my nephew for his 4th birthday. I did the houses of Patrick, Squidward and Spongebob. All are made of pound cake and covered in buttercream. The seaweed and "leaves" on the pineapple are made from green candy melts and the "sand" is graham cracker crumbs. To make things more interesting, we had to transport this one more than 2 hours and luckily nothing fell over.
