Slappy- Sewer Escape

I dragged the dummy toward the corner. I motioned to the metal drain down at the curb.
“The sewer?” Sara whispered.
I nodded. “It’s perfect.” Through the narrow opening at the curb, I could hear running water far down below. “Come on. Shove him in.”
Slappy still didn’t move or protest in any way.
I lowered his head to the drain opening. Then Sara and I pushed him in headfirst.
I heard a splash and a hard thud as he hit the sewer floor.
We both listened. Silence. Then the soft trickle of water.
...

The next morning, Sara and I came to the kitchen for breakfast together. Mom turned from the counter, where she was pouring herself a cup of coffee.
Jed was already at the table, eating his Frosted Flakes. “What’s he doing down here?” Jed asked.
He pointed across the table.
At Slappy. Sitting in the chair.
...

Sara and I both gasped.
“Yes. Why is that dummy down here?” Mom asked me. “I found him sitting there when I came in this morning. And why is he so dirty? Where has he been, Amy?”
I could barely choke out a word. “I… uh… I guess he fell or something,” I finally mumbled.
