NPCs/Waterfall

This fishlike monster will inform you of the Echo Flowers which fill the marsh. If you speak to the Echo Flower before talking to him, he will state how he feels that it is his only purpose.

"Loren"
This curious monster will ask you an assortment of questions about stars. Bringing an umbrella to them will prompt different dialogue.

They were created by Colin MacDougall.

Ferry
Ferry Monster is a monster that appears in Waterfall. The only part of it that is visible is a small flat pink face. Using this monster, the player can travel from one part Waterfall to another. After each trip, the monster gives the player 3G for stepping on their face and thanks them. It will do this an infinite amount of times.

Onionsan
Onion-san is a large aquatic monster that lives in Waterfall. It makes anime-esque faces and will follow the player through its room to keep up a conversation.

Onionsan claims that Waterfall is its "big favorite," although it expresses concern about the water getting very shallow of late. Onionsan is also very lonely, as shown by its desperation to engage the player in conversation. It explains that all its friends moved to a crowded aquarium in the city, saying that it can't join them because the aquarium is full. Despite this, Onionsan tries to maintain a positive outlook, saying that Undyne will fix everything and that someday it will get out and live in the ocean.

When walking through its area a second time, Onionsan tells the player that it's starting a band called the "Red Hot Chibi Peppers" despite it not knowing how to sing or play instruments.

In the credits of the True Pacifist Route, Onionsan can be seen happily lounging in the water at the beach.

Clam Girl
This rare NPC only appears when certain Fun Values in the game fall under a specific range. They talk about their neighbor, Suzy, and affirm that you should become friends with her.

Small Bird
This tiny but determined bird will carry you from one side of the room to the other. Its own special song plays when it does so. In the True Pacifist Ending Credits, the bird can be seen flying along with Papyrus.

Snails
These snails reside in Blook Family Snail Farm. One tells the protagonist to keep their head strong and reach far on their journey, while another counts dollar bills. One monster bought a shell from one of the snails, claiming that they were in need of a new house.

Bob
Bob is one of the four Temmies that sits near the entrance of Temmie Village. They seem to be a joke character since the Temmies found next to them speaks with a visual speech impediment, while Bob simply says "Hi. I'm Bob" in clean English. At the end of a True Pacifist Run, Bob will voice his thoughts the barrier being broken. Speaking to him will prompt the response "* This is a most pleasing development, no?"

They seem to be one of the few Temmies with the ability to speak clean English. The only other Temmie who shows this difference is the shopkeeping Temmie, who will speak in clean English if you deny an offer to sell an item.

Ragel
This mushroom will dance for you when interacted with, and his message changes based upon what When spoken to, Ragel does a seemingly innocuous dance (complete with its own music), keeping his head down so the two dots of his nostrils look more like eyes, before lifting his head and saying something to the protagonist, which differs depending on the player's actions during the game. He was created by Alexander Sward.
 * On a neutral run, if the player hasn't killed any monsters, he worries about how he's supposed to get to the surface, since he's rooted to his spot.
 * If the player has killed at least one monster, he suggests that the player has sinned. Trying to talk to him again after this will result in him telling you not to speak to him.
 * During the pre-credits walk around at the end of a pacifist run, he says he's happy, as he's found someone who will move him to the surface.

Box Guru
This cynical, aging monster will express their resentment of the puzzles of today. They insist that modern kids are hopeless, and will criticize the protagonist's attempt at their box puzzle.

They were created by Summer Wine.
