In the PB&J side mission of Borderlands 4, PJ tasks you with gathering the final piece for his ultimate sandwich — the mysterious “J.” What sounds like a simple fetch quest quickly turns bizarre, as the ingredients are nothing like you’d expect. By the end, you’ll uncover a hilarious twist: PJ’s prized “J” isn’t a “J” at all, but a “G”!

How to Start the PB&J Quest

To begin the PB&J side mission in Borderlands 4, speak with PJ on the eastern edge of the Ruined Sumplands, just east of The Marrow Narrows. He’ll be waving to you near his house, which is located next to the water on the shore.

How to Complete the PB&J Quest
Gather some goop off a beached buoy so your new Ripper buddy can assemble the fabled PBJ.
Pick up J
After accepting the quest, head east into the ocean. There will be little land masses that you can jump across. Alternatively, you could simple swim or ride your vehicle. When you reach the larger island, take the J from the buoy washed ashore on the island.

Give J to PJ

With the goop in hand, return to PJ and place the J on the table next to PJ. After some fun banter, the quest will complete.
