(Pepper, this includes the block destroyers, so tag along if you need to!)
Ruby's Nemesis, Pheona, the owner of the Block Destroyers, is furious that the Block Destroyers didn't do her evil deed, and then she takes their matter into her own hands, and casts an Illness curse on the whole entire NumberUniverse, causing all NBs to lose their Arms, and their arms get replaced with evil ones. Pheona controls the infected. Find a way to stop Pheona, before its too late.... Friendship won't fix it, no, no.... something else will. The power of All NBs + The MHB sisters. Pheona will try to play tricks to slow the process down. Let's begin!
In Pheona's Secret Office, in Evil HQ....
Pheona: Wow, Zach was too busy to know, he and the Block Destroyers had to do my evil lil deed! Ha, is he too dumb to notice? No matter.... to get my revenge, I'll cast an Illness curse on the NBs to start them a conflict. Evil laugh as she casts the curse on the NumberUniverse Ruby's definitely gonna be screwed now!
