Glee Cake

So one of the 12 year old girls I teach in Church invited me to her birthday party! How could I turn her down right? And for her present, what else, a cake of course. I called her mom to see if I could make it and asked if the party had a theme, Glee. What is a 12 year old is doing watching Glee, don't ask me, I just make the cakes! I wanted to keep it one layer and simple, but wasn't sure what to do so I googled it and stole a couple ideas to combine together.
