The Traveling Sisters Three
From the Super Mario Wiki
The Traveling Sisters Three are three Toad sisters. In Paper Mario: The Thousand-Year Door, the player will encounter them after every chapter, like Dupree. They are all triplets, and they seem to enjoy travel (as they continually move throughout the game's chapters, except chapter 2, where they can't be found, and chapter 8). However, according to Goombella, they seem to do little adventuring during their travels. Three pigs in Twilight Town bear a resemblance to them, and Goombella will even say they look familiar in her tattle. They speak in the same manner, with hearts at the end of their sentences.
Near the end of the game, after beating Chapter 7, they will be on Keelhaul Key enjoying the cold water. They will still be there after the game is beaten.
