The Ghostly Witches are a trio of ghost-like witches featured in the film Goosebumps 2: Haunted Halloween.
The Ghostly Witches were originally inanimate wicked witch hats displayed in the costume section of Fred's Pharmacy. However, Slappy the Dummy brought them to life using the incantation "Karru Marri Odonna Loma Molonu Karrano". The witch hats leapt from their shelf and spun around until they grew bodies with glowing green globe-shaped heads with blank faces and broomsticks for transportation.
The Ghostly Witches came across Sonny Quinn, Sarah Quinn, and Sam Carter while they were seeking Tommy Madigan for Haunted Halloween. The witches were mistaken by Tommy to be "awesome costumes" until one of them hissed at him, with a ghostly face appearing on her blank head. They immediately abducted Tommy and his two cohorts and fly up into the sky.
The Ghostly Witches are later seen assaulting the police force of Wardenclyffe, New York with green fireballs even try to attack R.L Stine before he got back into his car and attacked Sarah as she went after Slappy at the Tesla Tower. They were last seen being sucked into Haunted Halloween by Sarah along with all the other monsters Slappy brought to life.
