Get some colored paper and make pac men and hang them everywhere...including peeking in windows and the like.

My little cousin's birthday party is on Saturday, he's turning 3. He loves pacman so that's the theme of his party. His mom asked me to make decorations for his party since she can't find any pacman party decor in stores. Any DIY pacman decor ideas I can do? I only have a the rest of today, some of Friday, and some of Saturday so nothing to crazy please? Thanks guys :)
