The Yellow creature called Pac Man is afraid of little ghosts so to keep him out of you home you can get some ghosts but most ghosts are more annoying then Pac Man so that is not a real solution.
But now there are ghosts lamps. They look like ghosts but they are just lamps that turn them selves on when it gets dark.
They come in Blue, Yellow, Red and White. so you can choose your favourite ghost color.
You just plug them in a USB port and you are good to go.
Come have a better look at these cute Pac Man Ghost Lamps.
