Closet Monster

From Charmed

When Piper was six she was terrified by the "Closet Monster". Prue managed to convince her sisters that it was real. This is reminiscent of Phoebe's fear of the Woogyman which turned out to be real also and is comparable to the Water Demon and Slime Demon in body structure.

The monster is an amorphous blob, shapeless and almost colorless with two dull, coal-colored eyes set deep into its boneless figure. It has sharp pointed fangs. Unlike Phoebe's Woogyman, the Closet Monster did not have the ability to possess innocents.
