Happy 3rd Birthday Tristan!

My nephew Tristan is a Spongebob fan, so when I asked him what "present" he wanted for his birthday, he said, "A Spongebob balloon!!!!!" I decided to leave that up to his mommy and made him a cake instead. I colored the batter yellow in order to make his insides still look like his spongy self, and poked the cake and poured in lime Jello to give him the "mold" effect. I used the cool whip frosting recipe for the majority of the cake, and used chocolate frosting for his pants. I left out the lime Jello for that part so it wouldn't taste funny with the chocolate frosting.
