Clog his stomach!
You take a candy wrapper you were saving and stuff it in a hole that's
releasing acid. Sure enough, the wrapper is indigestable, and clogs
the hole. No more acid. After a while, the gorilla releases you into
the dragon's small intestine, not realizing you are still alive. The
small intestine was indeed, very small. And smelly. And you weren't
the last meal to arrive. But eventually, the dragon lets you out and
walks away. You are in a dark alley. Now
what?
