Barney Bumble IS in the movie, he make a couple of appearances and wraps the movie up with the gang all together again. The guys run a dispensary and the villains from I Got Five On It 1 and 2 are finally released from jail full of revenge.
Barney Bumble is not in the film. His friends run the pot shop.
They keep getting g better and better. The scene with the deaf guy almost made me pee!!!
