Undertale Wiki

Tra la la. I am the riverman. Or am I the riverwoman...? It doesn't really matter. I love to ride in my boat. Would you care to join me?

First interaction with the River Person

The River Person is a hooded figure who provides transportation services to Snowdin, Waterfall, and Hotland on their wooden boat for the Underground. The protagonist can request a ride to any of the locations above if they reach Hotland on any route.

During the trip, the River Person has a list of messages they can say at random, often being a hint to a secret or an allusion to something in the game, or just something cute. One hint—the hint to finding Temmie Village—is specifically scripted to occur.

With Known or Possible Meanings

Message Meaning/Allusion
"Tra la la. Remember to take a break every-so-often..." Possible reference to Ness's father in EarthBound who would occasionally phone Ness and remind him to take a break.
"Tra la la. Did you ever hear the old song coming from the sea?" Possibly alluding to the Sound Test room, which can be found near the riverbank west of Snowdin with a fun value of 65. It could also be a hint at room 70 (room_tundra_dock), where the Wrong Number Song can play if the fun value is in between 2 and 39. It might also be forshadowing Onion's dialogue in Deltarune chapter 2, where he mentions hearing a song "coming from the sea".
"Tra la la. I heard ASGORE has a favorite food." Eating the Butterscotch-Cinnamon Pie during the fight against Asgore reduces his AT and DF.
"Tra la la. I heard spiders have a favorite food. It's spiders." A hint to an alternate way to defeat Muffet.
"Tra la la. The piano plays the tinkling song. Hmm... tinkling." Hinting at the solution to the Piano Puzzle.
"Tra la la. You can never have too many hot dogs... Sadly, this is not true." If the protagonist buys a hot dog from Sans with a full inventory, he places it on top of their head. He continues to stack 29 hot dogs on their head before stopping, saying "i'll be 'frank' with you. as much as i like putting hot dogs on your head... thirty is just an excessive number. twenty-nine, now that's fine, but thirty... does it look like my arms can reach that high?"
"Tra la la. Don't snoop behind people's houses... You might be mistaken for a trash-can." A hint directing the protagonist to check behind houses for secrets, particularly the back entrance to Papyrus and Sans's House.
"Tra la la. The angel is coming... Tra la la." Alluding to the legend of the Delta Rune.
"Hum hum hum. Hum hum hum. I'm having a little concert." A hint on how to get the yellow text for Shyren.
"Pet pet pet... The neck stretches infinitely into the cosmos. ...Don't worry about it." Hinting at the Lesser Dog petting easter egg.
"Tra la la. What's a game you can play with a dog? Asking for a friend..." Possibly referring to how the protagonist can use the Stick in battle to play fetch with the Snowdin Canine Unit and Endogeny.
"Tra la la. Temmie Village... the room before the darkening lantern room..." A hint on how to find Temmie Village. This is always used the first time the River Person's boat is in the shape of a dog.
"Tra la la. If it's hot or cold, you can count on me." Refers to the fact that the River Person can stop in both Hotland and Snowdin.
"Tra la la. Humans, monsters... Flowers." Flowey is not a human or a monster, but an entity all on his own.
"Tra la la. Beware of the man who speaks in hands." Presumed to be a reference to W. D. Gaster. It can also be a reference to Toby Fox/the Annoying Dog.
"Tra la la. Beware of the man who came from the other world." Presumed to be a reference to W. D. Gaster, Sans, Toby Fox/the Annoying Dog, or So Sorry. The "world" is speculated to be the world of Deltarune, a sister game by Toby Fox confirmed to take place in another world from Undertale.



  • Sometimes, the River Person's boat has the face of a dog and runs on top of the water. This is possibly a reference to Mother 3 when Lucas rides his Running Table.
  • The River Person is likely based on Charon, the ferryman of the River Styx in Greek mythology.
  • The River Person's gender is not decided, and they even dismiss it as not mattering. However, their sprite name is spr_riverman, hinting that their gender may have been intended to be male initially, as the dialogue for the character could have been made after the sprite was named.
  • The River Person is used for public transport in the Underground, as implied by calling Papyrus and Undyne.
