Petalburg

Petalburg is a peaceful village filled with flowers and found in the game Paper Mario: The Thousand-Year Door. Koopas, Toads, and a couple of Bub-ulbs reside in the village. The mayor of the town is an old Koopa named Kroop. Petalburg is where Koops, a member of Mario's party, hails from. The peaceful village used to be terrorized by the dragon Hooktail. Thankfully, Mario, Goombella and Koops put an end to the dragon's reign of terror.

Later in the story, Bowser and Kammy Koopa are in Petalburg. Bowser spots Princess Peach, and starts talking to her, only to find out it was a poster

Area Tattles

 * This is Petalburg. It's nice and warm here, and the air is sooo clean... Such a peaceful hamlet... There's a shop and an inn, so you buy stuff and rest. Oh, and one more thing... The river's pretty, but fall in and Nibbles will getcha!
 * This is Petalburg. The warm weather makes the locals laid-back and happy. Wow, and talk about unique personalities... Very... individualistic, to put it nicely. Or, not so nicely... Downright kooky...
