Candy could always teach Karn the ways of surviving in the streets. Just know the three basic rules that Candy used.1. Look cute and dirty when the rich people pass by and try to make them feel sorry enough to let them sleep in their guest rooms for a couple days.
2. If number one doesn't work, then try other methods in obtaining money and housing, like squatting in abandoned buildings or stealing money.
3. Buy candy
Well Karn is a natural #1. Well, looking cute at least. And cause people to think he's a girl. But he doesn't really take advantage of it.... It just usually ends up with him in a maid outfit.
#2 he wouldn't do because he tries not to steal. But he does makeshift his own shelters
#3 He loves candy and sweets said sooo no problem there
