<human>: Can you provide a brief rundown of the text in within 3 sentences?

My four year old niece came to visit me and asked to use the bathroom.

About less than five minutes later, the toilet regurgitated a whole roll of toilet paper, poop, pee and a LOT of water. She proceeded to try and plunge it herself and *flushed* it while plunging. Apparently a whole roll of toilet paper was not enough to cover her issue.

I was downstairs and discovered what had happened because I heard water running through my apartment air vents.

I ran upstairs and discovered 4 inches of standing water all across the master bathroom... along with everything else that the toilet rejected.

To my horror, the water was draining down the air vent on the floor (which, by the time I went downstairs to get a towel, it had already leaked through the ceiling vents in my living room, leaving watermark stains across the ceiling. My California king-sized sofa was under the final vent (the entertainment center was under the other vent).

I am less concerned about household furnishings (thank goodness for removable covers... however I need to buy more laundry soap and clorox wipes).

This leaves me with the problem of the poop water in my vents. Help me, please. I am renting this place. I am at an utter loss of what to do about the poop water in my vents and the stains in my ceiling. It's already stopped dripping, but how do I know if it's dry and how do I get the smell out and disinfect my vents? I've already used bathroom cleaner on the ceiling and a couple of other areas. It's helping a little... but what do I do for the rest of it?

In the meantime, I'm going to disinfect the entire bathroom. I await your suggestions.
