Bell’s string

About
Bell‘s string is an item that is a body part of Bell. It is a long, thin, black string (blue in BFDI and BFDIA) that leads to a changing or unknown location.

Bell herself appears to know where her string leads to, as she “prefers not to tell”.

It has been shown that at times, Bell can willingly detach herself from the string, as she is sometimes shown without it. She can also move whatever her string leads up to, as she she has been shown at different places with a string leading straight up.

In “Today’s Very Special Episode”, Eraser was curious about what Bell’s string was attached to, so he decided to climb it. This caused a chain reaction where many of the contestants decide to climb Bell’s string as well. However, this conflicted ended when Bell asked Lightning to zap her, because the climbers were electrocuted along with Bell.
