There is only one play place but beyond it is infinite play place('s) full of endless winding turns and contraptions of unknown purpose. Many go mad trying to find their way back to the mcdonalds realm but never find their way. Legends are told that great resources rest deep in the inner workings of the play place but anyone who dares to go too far in is never seen again to tell the tale. Strange rhythmic clanging and vibrations faintly emanate from far in and oddly, small biological organisms such as spiders and worms turn up around the entrance. People in the midst of night are called into the depths from time to time in search of something unseen to others.
No, I can see a lot of bacteria flourishing there, nurturing itself by the infinite amount of """SUBSTANCE""" this hypothetical McDonalds has.
