Starry Nights

Bill a dream demon decided he wanted a child to help him take over the world. At the time dipper was twelve bill took some of dippers DNA and combined it with his. He created a small ball of life and waited until it hatched. 4 years later dipper comes back to gravity falls without his sister because she is still a home back in California. Bill pays a little visit to his pinetree just wanting to stay with him trying to keep their kid a secret.

BTW I own nothing but the child and the surprise 😉
