My Christmas present to all Abarat fans out there!
If you dont know what this creature is, I can tell you this is one of Christopher Carrions creepy Nightmares.
Carrion uses these creatures to send nightmares to his prisoners and scare them to death with fear. These Nightmares are monsters that swim from inside Carrions brain into his collar.
I dont own Abarat or the characters, it belongs to Clive Barker.
