Best of Two Worlds by Lady Reader04 reviews
Bella had a hard life. Her mother died when she was 4, her "uncle" disappeared when she was 12, and her "cousins" were long gone. One day, her uncle's ex-assistant tells her to look through her uncle's research about the town's most cursed site, Mt. Ebbot. As she reads, forgotten memories return: fish with spears, goats with pie, flowers that talked... What was under Mt. Ebbott?

Get dunked on by Valrex5 reviews
After a serial killer obliterated a good portion of the Underground, Sans, the considered weakest monster stood against it as a last stand. After pulling of a cheap trick, he just expected to the human to come back and try again but... that didn't happen. My take on what would happen after the 'get dunked on' moment if the human didn't reset.

Two Worlds: Two Souls by Halloween Witch reviews
I flinched when I felt the rocks move from under us, no longer able to hold our weight. I latched onto my sister just as the earth shattered beneath us and gave way to a free fall. Frisk screamed and I struggled to hold her to me. To use my body as a cushion when we made it to the bottom. One way or another, I wouldn't let her die.
