a co-worker friend of the bfs needed a cake for her daughters 7th birthday and she wanted it spongebob themed. she didn't want a fondant covered cake. i think the star tip gave it a more realistic look than the fondant would have. spongebob was made from modeling paste with only the dots on the cheeks and strips on his socks painted on.
here is a close up of spongebob. i'm very happy with how he turned out!
