Possibly while drinking B3, the guys down at R&D decided to increase the potency of the stuff, taking Bouncy Bubbly Beverage to all new levels of sheer Zow! The final distilled and concentrated version, dubbed PB3, achieved what the techs are now calling "weapons grade B3", meaning that the effects are so dehabilitating as to be possible to use as a weapon. In short, it's powerful stuff.

Part 1: The Presentation
My favorite part of the PB3 process is describing the presentation in R&D. Technicians will don full body suits, enter a heavily fortified chamber of R&D (with vapors and smoke issuing forth) and return with a barrel of this stuff on a big cart. They will then, in very slow deliberate motions, scoop some from the barrel (as depicted) and pour it into whatever transport vessell the team has been issued (B3 dispensor, liquid grenades, etc). The team will then reverse the process, and then destroy the full-body suits in front of the troubleshooter team. For even more effect, have another R&D tech giving directions from a sealed room while checking off items on a clipboard. To REALLY shake things up, have a failure on the checklist whereas one of the two techs moving the large barrel will get some on him and go running and dive into a "safe pool", and then have to go into a room marked with "observation" over the door.

Part 2: (Don't) Let it Breathe
The vapors issued from PB3 are quite intoxicating... and somewhat toxic. Not REALLY toxic, it's just that they affect the brain in the same way as sniffing glue or fuel. Anyone getting a whiff will get a bit lightheaded, perhaps even a bit buzzed. Continued exposure will lead to drunken stupor, coma, and death. It would take quite a while to actually kill someone with PB3 using the vapors, but not impossible.

Part 3: Not to be used externally OR internally
Actually TOUCHING PB3 produces effects like drinking BBB. It's very intoxicating, and generally clones will get sloppy drunk and happy. They'll start to babble secrets, discuss (at length) their personal views on a wide range of topics and eventually begin to get agitated at anyone who doesn't come out and agree with said views. Eventually, they'll get rather disagreeable and downright violent. Finally, the clone will pass out and have very bad dreams.

Part 4: Sip, don't gulp.
Sooner or later someone's going to drink some of it, and this is bad. PB3 has several nearly instant effects:

Small Sips:

1. All rolls are to be taken at -10. Regardless of what they're for.
2. The clone will lose all sense of balance and will randomly lose their other senses for short periods of time.
3. The clone's mutant powers will probably kick in. Some (like regeneration) will be hard to percieve, others will be pretty obvious.
4. The clone may pick up a NEW mutant power. You can roll or simply assign this at will.
5. Until the clone dies and regenerates, rearrange any moxie and chutzpa skill points.
6. The clone will quite a few hit points, and will have to roll to survive the shock and toxic impact on his/her system.

Eventually, the clone may recover.

Anything larger than small sips:

1. The clone will pass out and will lose hit points until they die, which will take several gruesome rounds.
2. The clone will start to pick up mutant powers at random, and will start to use them uncontrollably.
3. The clone's body becomes toxic to touch, and will emit vapors (see above).
4. The clone will explode in a burst of PB3 and gore. See if any of it gets on other clones.

Part 4: Neither shaken nor stirred
Finally, PB3 is a bit unstable. The "bubbly" part (Carbon Dioxoide) combined with the unstable part, means that if the PB3 is shaken, dropped, rolled, thrown, or otherwise agitated, it could explode. It is, as already stated, not healthy to touch, smell or drink, so having it splashed all over you (and possibly getting some in your mouth) is not healthy. Effects of vapor AND touch should be observed, plus bonus damage from shards of schrapnel from whatever was holding the stuff before it blew.
