Janitor

Description
Janitor, also known as John or Jan, was hired to work as a janitor at Doug's Planet Coaster theme park due to Biff Bezos now working at The Grocery Store. He was very bad at his job (just like Biff) but Chat loved him anyway. It is possible he is the test donation message guy, as he is also named John. Janitor and Biff look identical, and it is possible they are the same person.

Dark Secrets
During the stream where Janitor was introduced, Doug used NovelAI to generate some information about him. Doug never would've expected what the AI would come up with.
 * Jan was discovered to let children drink his cleaning products, just to then eat their corpses; the children soon noticed this strange behavior of his and reported it to their parents. He has started hiding the remains of the corpses inside the The Theme Park's bins ever since.
 * John's wife, an evil witch, once tried to kill him while disguised as a tourist, after she got "done with him", she gave birth to a child looking exactly like him.
