Before I start writing anything, I have to give the idea courtesy to my 4 yr old little monster.Below records a conversation between my son and me.
Me: Do you know what is a rainbow?
My Son: I know, I know. It is a unicorn sitting on the cloud and putting poo poo which comes in rainbow color.
Thanks to my daughter, my son is also fascinated with Unicorns. We had a combined rainbow party for them ( lucky me, both are march born with some days apart and 2 years ofcourse ;)). I didnt have any clue as to how I would make a boyish version of a Rainbow Unciorn cake. That is when my son gave me this idea
