You examine the grate under the murky water.  Unlike most sewer drains, no whirlpool has formed; the water just isn’t draining. Look around for anything to help.

You step onto the stationary merry-go-round and head to the middle. You open the door and pull out a crankshaft hook replacement part and a long pole. “Perfect,” you say to nobody in particular. You wire them together to create a hand-dandy sewer-unblocking tool. 

You insert the hook end into the sewer grate; something is blocking it; you can feel it.

---

You pull back, thrust the hook, and twist. It gives. 

A sudden gurgling sound is heard.  A fast rush of water goes around your feet, and a sharp burst of air pops as the water rushes back into the sewer.

You pull out the source of the blockage: a multicolored clown wig. It’s a bright, bouncy costume hairpiece. It features big, tight synthetic curls shaped like a large afro. The hair strands show a full rainbow of shades: red, orange, yellow, green, blue, and purple. It uses a stretchy mesh cap with a soft elastic edge to fit most heads. You examine the tag.

You see an unusual FIND THE KEY WITH THIS SYMBOL (this is be added later) with a faded tag number 20-8-5 5-25-5.
