Kroop

"I appreciate that, Murphy! They ARE nice eyebrows."

- Kroop

Kroop is a Koopa Troopa and the mayor of Petalburg. He is an elderly Koopa, and as such, has much life experience. This experience serves him and the citizens of Petalburg during times of peace and during times of crisis. Kroop has large bushy eyebrows and a wrinkled face.

During the events of Paper Mario: The Thousand-Year Door, Kroop provides Mario access to the Shhwonk Fortress, the site of the Moon and Sun Stones needed to open the path to Hooktail Castle.

Kroop's hearing is not what it used to be. As such, the old Koopa calls Mario by the name "Murphy" throughout the plumber's adventure.

Kroop also had a trouble in the game. He wanted someone to talk to him. After Mario listened to his long speech, Kroop rewarded the plumber with a Turtley Leaf.

Trivia

 * Kroop's name is the word "croup" misspelled to appear similar to the word "Koopa". Strangely, croup is a disease that ordinarily effects children no older than three years old (which is quite ironic, considering Kroop's implied age), although the fact that it involves breakdown of the lungs (a scenario commonly associated with rather old people) could've been the reason Kroop was named after it.
 * It is known that Kroop, at one point, had a wife; however, he appears to currently be a widower.
