Swamped

You remember closing the door to the storage room, but you happened to notice it was open a little. And you saw the doctor and both nurses at work on your way here, so they wouldn't be getting things out of it.

Seems worth investigating. You walk over to the door, and take a quick look inside.

All you see is a lizard. Not the same one as before, though - this one's black, with blue stripes. And about twice as large, to boot.

"Do you talk?" you ask it. It responds by spitting at your shoes. Doesn't seem particularly friendly, but not all that hostile either.

For a moment, you wonder if this is the eavesdropper. But then you spot something else that wasn't in here before.
