I am doing a birthday cake for my son's friends daughter at the end of october, she will be 3. The cake started out as hannah montana theme, then the partents (which are 20 and 19) switched to a princess theme, then it went to a fancy nancy theme. now they have changed it to a monster theme, they want "happy" monsters. any ideas will be greatly appreciated.

I have a Valentines Monster in my photos, he's cute , happy and super easy to make.

You could change the heart to a balloon or happy birthday sign.

Very cute, Cakemommy!

The first thought that popped into my head was the book "Where the Wild Things Are."
