I don't know

"Oh," the spirit says, sounding a little disappointed.  "Do you know I'm a little teapot?"

"Of course!" you say.

Blue lightning shoots at your feet. "Then sing it!"

You sing "I'm a little teapot," complete with moves.  It appears to mollify the spirit.

"I'll let you live," the ghost says.  "But don't come back!"

You are forcibly ejected from the Dusk to Dawn, landing outside.  Shaking yourself off, you decide to climb the fence and get out of here.
