Marceline's Hobo Camp was a small camp that was situated in an Old Industrial Park. It was a place that Marceline used to live or take shelter in many years after Simon left her. She regularly went vampire hunting from this camp.
The camp consists of a very small shelter with a poorly made roof over a small mattress. Beside the mattress lie computers, plants, water line pipes, livers, Brussels sprouts, spinach, turnips, lima beans, and barrels with skulls and crossbones on them and water inside. The area seems to be very wet and messy overall.
- Marceline now lives in her cave.
