Pacman has been going around and around for so long that he has worn this object!
This object has the same properties as the Möbius strip.
It's got only one side: just try to follow Pacman's track, you'll find that he will eventually come back to exactly the same spot. But he will come very close to this spot three times before reaching it at last. Pacman won't stop there, of course. He will keep going around and around...
