Bill Cipher was a Dream-Demon that is worshipped by Crazy Cult Guy and other shy guys.
Appearance[]
Bill was a triangle with an pyramid design, therefore resembling the Illuminati symbol or the Eye of Providence, with an eye in the middle. Among the bottom part of his body is a brick pattern.
He is created when one of the Green Shy Guy cultists accidentally fell in a cauldron. He is seen dancing to the Bill Nye theme and grabs OnyxKing67. He then flies into Mario and Dave and explodes.
