Only One Lightbulb

You are playing george, a young boy who wakes up in the middle of the night.

"Oh god, a candy bar would be nice" is all you can think about.

With only one single lightbulb you need to get to the fridge. But be careful. Ghosts are around everywhere at this time. Don't let them catch you!

Why there are no other lightbulbs in the house? Well, george is a little boy, how do you think should he afford them?
