Explain/Mandelly
Mandelly is a concept created by Wiki Camp 2 user QWillow.
Mandelly is a fictional competitor implied to exist with the other competitors. Mandelly is inspired by both the Mandela effect, a term coined by paranormal researcher Fiona Broome to describe a phenomenon of shared false memory; and mandalas, sets of geometric patterns.
The concept of "a contestant that is only referred to through red links" was first brought up by QWillow, with the idea consisting of all references to them being secondhand information, i.e. competitors talking about them, trivia sections, opinion pages, etc.; however would not actually exist. Mandelly was first referred to on Emoticon/Opinions. It would later be referenced on other pages, including Padlock/Opinions, Nurse Cap's matchups, and Chronological list of contestant related events.
Due to the character's nonexistent nature, it is intentional that all details regarding them, their personality, their appearance, etc. are made up, and can be even directly conflicting with each other.
As of September 30th, 2023, the page for Mandelly was deleted, obscuring the already flimsy information about them.
