It's subspace, for all you know that might be how his door
should be.
And should you feel the need to point out my mistakes I shall point out yours:
I know for a fact that the pacman ghosts have names other then Red Orange Blue (he's actually cyan...) and Pink. And I know for a fact they are as follows:
Red= Blinky
Pink= Pinky
Cyan= Inky
Orange= Clyde
I hereby shall go further into the history of the ghosts as I begin to question why you seem to have appointed Clyde as the natural leader as he is in fact the slowest of the four and the translation from his Japanese name is 'stupid'.
You may think I know a little too much about these ghosts. I may agree.
