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 the protagonist reaches Hotland on any route.
During the trip, they have 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. At least one hint – the hint to finding Temmie Village – is specifically scripted to occur.

With Known or Possible Meanings
|"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 at fun = 65.|
|"Tra la la. I heard ASGORE has a favorite food."||Eating the Butterscotch-Cinnamon Pie during the fight against Asgore will reduce his Attack and Defense.|
|"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 Room 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 will place it on top of their head. He will continue to stack 30 hot dogs on their head before stopping, saying "sorry, thirty is the limit on head dogs."|
|"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 the Papyrus/Sans residence.|

- The River Person is likely based on Charon, the ferryman of the River Styx in the Greek Mythology.
- The River Person's gender is not decided, as they even dismiss it as not mattering. However, their sprite name is spr_riverman, hinting that their gender may be male (or at least was intended to be, 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.
