The Shinx, asleep, is calm as you adjust him to face straight up. Once he is in that position, you stand up with one hand, keeping the other one on the Shinx to keep him vertical, and drop onto the Shinx as he is pulled up your butt. A sensation fills you as the Shinx awakens, beginning to struggle inside you.
"You promised you wouldn't eat me!" cried the Shinx.
You smirk as you say, "I didn't, you are up my anus right now."
The Shinx's continuous thrashing pleases you as it eventually comes to a stop. The Shinx is doomed as it gives in, becoming a part of you.
