Masked Wibbler

An unseen but ever present malevolent entity responsible for the slight moving of one’s bag from the position one remembers placing it in, to a new position very close to but not quite the same as the original position.

Person 1: Have you seen my bag?
Person 2: yes, it’s under your chair still
Person 1: oh yes, but not quite where I left it
Persons 1 & 2: Gasp! The Masked Wibbler!
