Blather, Rinse, Repeat

wendywoowho thought it was a good idea:

You are... A Peanut Butter and Jelly Sandwich!!!

You have two distinct halves that come together as one.
Both sticky and sweet, your proportions are often meddled with,
but you are nonetheless a tasty treat. Your compassionate
side appears when you selflessly shed your crusts
in the name of motherly tenderness.
Everybody loves you, but they love you even more
when your buddy, Glass "o" milk, shows up.
The key decision for you in the next five years will be,
"Should I be cut diagonally or horizontally?"

So, I call upon you intelligent, creative, dare I say mischievious, people.

There's a room that I need to decorate as though an 8 year old girl lives there. It happens to be my boss' office, but that's not important right now.

My question to you fine folk is what should I make sure to have? Right now the lynchpin of the decorating project is a poster of a pony and/or unicorn, which I don't actually yet have. I do have a couple of teen magazines with glossy photos of Ashton and JC and whoever.

The boss comes back on Wednesday, so mail order is out of the question.

So:

a) what do I need to get to communicate "8 year old girl"? (No points deducted for being obvious.) b) where can I find it on relatively short notice?
