Waterfall

Undertale guide · The player enters the dark, cavernous region after Snowdin

After escaping Papyrus in Snowdin, the protagonist journeys through Waterfall, a bioluminescent subterranean wetland filled with Echo Flowers and ancient monster history. You must navigate environmental puzzles, flee from the relentless pursuit of Undyne the head of the Royal Guard, and explore quiet settlements like Temmie Village. The area culminates in an unavoidable encounter with Undyne, after which you proceed forward into Hotland.

Enemies

Aaron

Can be spared by repeatedly flexing until he flexes himself out of the room.

Woshua

Cleans the protagonist with an attack pattern; touching the green water droplets allows you to spare it.

Shyren

Can be spared by repeatedly humming along with her until a concert takes place.

Moldbygg

Disguises as a standard Moldsmal; uncurling reduces its aggression and allows it to be spared.

Undyne

Changes your soul mode to Green, forcing you to block spears with your shield; to spare her, you must flee toward Hotland whenever your soul turns Red.

Shops and people

Gerson: Sells Sea Tea, Crab Apple, Torn Notebook, and Cloudy Glasses; also shares ancient lore regarding the Delta Rune and ASGORE.
Tem Shop: Sells Tem Flakes and pays for protagonist inventory items; can be funded to attend college to unlock the overpowered Temy Armor.

Tips

Buying Cloudy Glasses and Torn Notebooks from Gerson and selling them back to the Tem Shop is the fastest, safest way to generate unlimited gold in the game.
Giving the parched Undyne a cup of water from the water cooler at the border of Hotland is strictly required if you want to befriend her on a Pacifist route.
