Who Lives In A Pineapple Under The Sea?

Spongebob SquarePants!  Here is a cake I made for my son's 5th birthday. I saw a similar one online and thought it would be a fun and quick cake.  Problem was, I tried to use that gel type icing..I'm not sure why they didn't work for me, but rather than a nice gel line, i got blobs and runny watery sludge.  This cake certainly isn't my best work, but Jake loved it just the same.
