Sinny is the newer toon to be created in Joey Drew Studios. He was made to be Bendy's so called "clone" or at least him from a "different universe". He was only going to premier in one episode, but since children loved him, Mr. Drew decided to keep him around.

Sin is kinda like the opposite of Bendy. He is more light-hearted and doesn't like to cause trouble in the studio. He would do anything to help people. He's a kind bean.
