Quick notes

  • Toriel introduces life in the Ruins. Toriel meets the human near the beginning and guides them through early puzzles and encounters.
  • Meet the skeleton brothers in Snowdin. Sans and Papyrus greet the journey into the snowy region in very different ways.
  • Undyne’s friendship needs an earlier kindness. Undyne leads the Royal Guard and pursues the human in Waterfall.
  • Alphys connects Hotland to later route events. Alphys is the royal scientist encountered in Hotland and has a close connection with the robot entertainer Mettaton.
FIELD NOTE

The character names in a route checklist are progression requirements; ordinary conversations with every NPC are still optional discoveries.
