Pacman and Ghosts Costume Help!

[Momiji]

Make the opposite side of the ghosts blue, so when you pick up a power pellet, they turn around.

But if they're running through a hallway, there will most likely be people watching from both sides...

Well, people are just going to have to use their imaginations.

Or, you can make the fabric on the inside blue, so after the first runthrough, go hide for a second, and turn the costumes inside out.
