>CHECK CABINET
You carefully step around the filthy water, coming up to the sink.
The medicine cabinet is pretty bare, but for a single enormous pill. Like, seriously, you don't know how anyone would ever swallow this thing. I mean, you can barely get it in your mouth! It's large enough that the pill itself is engraved with a label; [i]Fast Acting Health Supplement. [/i] On the back are dozens of warnings, too small to be properly read. The cabinet has a mirror set into it's back.
>LOOK IN WATER
You peer into the toilet bowl. Doesn't seem like there's much in here; just some scummy water.
You go ahead and close the toilet seat and climb up, looking into the toilet's reservoir. There is something in here! A small plastic baggie, with a piece of paper in it. You reach in and grab it. It's the second half of the song!
You can't see what's in the murky water of the tub from here. The water is almost opaque, it's so dirty and stagnant. You could feel around in the tub of you went up to it, but you're reluctant to step through the water barefoot.
>TURN OFF WATER
You don't see any way to turn off the shower's drip from here, and a quick fiddle with the various bits in the toilet shows that they're mostly stuck.
