I would be "The monster under somebodys bed" And then when the parent came I would turn invisible and then scare here RIGHT in her face! turns into cacooey.
I would breathe down stalkers necks and make them paranoid. On christmas I would pretend to be the three ghosts of christmas past, present, and future. On halloween I would go tricker treating and be the last trick or treater. When I get my candy I'll take of my sheet revealing that I'm a ghost and start an urban legend.
