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 Stone Keys needed to open the path to Hooktail's 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.
