Ep 6. Pen Pal From Another Planet/Roman Grinders

Jack Knife has a new pen pal that he's always texting. The more Lil Rob learns about Jack Knife's pen pal - all of them very odd -- the more Lil Rob thinks Jack Knife is being punk'd by someone - and he suspects that it's one of the Grinders. But the truth may be even stranger as Jack Knife's pen pal just might be out of this world...literally.
