Aside from the already decrepit state of the sixth floor, there doesn't seem to be anything unusual happening. The students find themselves left curiously... alone. No motives, no murders, no Monobear, it appears. Have they done it? Have they survived long enough that the bear and presumably its master have gotten bored and moved on? Or are they just hanging by a thread, waiting for the other shoe to drop...
With a sound like buckling metal, and an almost painful sounding groan, there comes an almighty crash from the top of the building, audible even from the first floor. With really nothing else to do, the students ascend to the sixth floor to investigate...
"WHAT IS THIS?!"
Popping up from nowhere (as usual), Monobear lets out a yell of indignant rage. The water is now starting to come up to the student's knees, which means that the bear is almost up to his arms in it. He splashes around irritably.
"Those bastards are still messing with my building!! You'd think after some chlorine gas and machine gun fire they'd get the message, but no, they just have to go and mess with my beautiful mall! I'll rip them to shre--"
As he says this, another hole cracks open above him, dumping a brand new waterfall on his head.
*glubglubglubglubglub*
Monobear momentarily silenced by the ceiling's ernest attempt at drowning him, the students ears catch something odd. Is that a... music box tune? It doesn't appear to be coming from downstairs, or any of them, or any of the shops. In fact, it's coming from the hole above them. It's out of their reach, and the water is pouring down from all sides, blocking their view, but they can hear it, an old and familiar tune - London Bridge is falling down, falling down, falling down...
"Geh!! I've HAD IT! FIRE ALL TORPEDOES! LAUNCH EVERY ZIG! I DON'T CARE IF IT'S COPYRIGHTED!! I'LL KILL 'EM!"
He wades off through the water shouting and swearing, eventually disappearing. Within a few minutes, the water starts to slow from above, eventually coming to a dripping stop. It drains from around their feet, cascading down the stairs. Should any of them go to try the taps now, they may find themselves disappointed. The water appears to have been shut off at the mains. Uh-oh. Hope you're not too thirsty.
