Familiar Leash
From Growtopia
Familiar Leash is a Halloween pet leash, obtained by sacrificing a Black Cat Leash to Growganoth. A black cat with red eyes and a green witch hat follows the player around when equipped.
In-game description: Mrow HISS! This black cat contains the very essence of dark magic. Unfortunately, it's a cat, so you can't get it to use the magic for you."
