The Pimp-Boy 3 Billion is a standard Pip-Boy 3000 that has been "pimped out" with what appears to be gold and silver plating as well as encrusted diamonds. Once received, the Courier automatically replaces the standard Pip-Boy 3000 with the Pimp-Boy 3 Billion. To switch back to the original Pip-Boy, they can simply talk to Mick about it.
