The Black Puffle Upgrade is an upgrade you can get while playing RPA: The Ultimate Battle. To get this you must buy it from the Robber Store for 10,000 coins. It allows you to call in selected black puffles, including the regular ones (Flare, Dubstep,etc.). Unlocking this will unlock Agent Black Puffle in the game. If you use this upgrade while playing as Agent Black Puffle, you can call in a special Dubstep Flare puffle. It involves a black puffle with headphones producing blue fire.
