Swamped

It looks like there's a floating device connected to a chain. If enough water goes in, the little thing floats up, and when it floats up high enough, the chain gets pulled. That's probably what makes the alarm go off.

If you could reach your hand in, you could just pull the chain. But the opening's too thin.

The next best idea you've got is to hit the chain with your wet sock. If that fails, well, you've got another sock. Also your work gloves. Four tries ought to be good enough.

You slip the sock into the drain and try to aim for the chain as best as you can.

Your luck's better than you hoped - the sock snags on the chain before you even let go of it. So all you have to do is pull. Might even be able to get out of this with nothing worse than a hole in your sock.

As you pull, you start hearing bells in the distance. That's done the job, then. Now you can get back to finding your runaway. You pull the sock loose and stuff it in your pocket - not worth putting it back on right now.

The buzzing is a lot louder now. You turn around carefully.

What you see is a mass of bugs in the shape of a man.

Not just any bugs, though. You've studied insects enough to realize what's off about these ones.

They're all dead.

Doesn't seem to be stopping them from moving closer, though. And while you can give a pretty solid punch, dead bugs probably aren't going to feel much from one.

So what can you do?
