Marceline's Hobo Camp was a small camp that was situated in the Old Industrial Park. It was a place that Marceline used to live or take shelter many years after Simon left her. She regularly goes vampire hunting from this camp.
It looks like a very small shelter with a poorly made roof over a small mat. Beside lies computers, plants, water line pipes, livers, Brussel Sprouts, spinach, turnips, lima's and barrels with a skull on it and water inside. The area seems to very wet and messy overall.
