Who lives in a pineapple under the sea?

I made the cake for my son's 5th birthday. He wanted a Spongebob castle cake. I cheated on this cake. Since I don't have an edible image printer I printed the from my regular printer and laid them onto a piece of fondant I cut to match the image. The castle parts are from the Wilton Castle set. It is the first time I used it. They were kind of a pain to cover in fondant. I ran short on time so I didn't have time to add his name to the cake :(

OH! I used cinnamon toast crunch cereal for the dirt. I crushed it in my food processor. It tasted so good!! Much better than anything else I have ever used for dirt.
