When does Mr. Pickles return?

Mr. Pickles is an adult animated horror comedy slasher series. The series was created by Will Carsola and Dave Stewart for Cartoon Network's nighttime programming block Adult Swim. The first episode of season 4 was a surprise series finale, replacing the show with a new spin-off/sequel series titled Momma Named Me Sheriff. The Goodman family and their innocent and dimwitted 6-year-old son Tommy have a satanic border collie dog named Mr Pickles.
