   Summary

   You've fallen into the underground, and your time there hasn't been quite so pleasant. What's worse, you've found yourself in the care of Doctor Gaster, whom you're convinced is ready to experiment on you.

   Turns out, the scientist is much kinder than you expected, and there are quite a few...interesting perks to letting him study you.
