You were one of Car's 47 friends and he finally invited you to his house!...which was a cave in the Car Mountain....but okay-

"Hehe,i hope you don't mind the mess!"

Car says. You look around the apparently empty cave before Car turns on a...nonexistent light,revealing a actually organized room. Welp,maybe it was pure black and that's why it looked empty. Car told you that he lived with someone else but...You only see him.
