Pennington

Pennington is a Bumpty detective from Poshley Heights in Paper Mario: The Thousand-Year Door. Mario first meets Pennington on the Excess Express, where he takes Mario under his wing (so to speqk). Pennington and Mario must solve the many mysteries that occur on the train. Of course, Mario solves all the mysteries with no help from Pennington.

When the Excess Express arrives in Poshley Heights, Mario heads to Poshley Sanctum to find the Garnet Star. However, the sanctum curator is unavailable and the entrance is locked. However, Pennington soon arrives and unlocks the door, revealing that his real profession is being the manager of the sanctum. Being a detective is just an obsession of his.

Although he is the curator of the sanctum, he does not know where the Garnet Star is located. The only item on display is a replica of the Garnet Star, probably to protect the real star from falling into the wrong hands.

Although Pennington claims to be a great detective, he constantly mistakes Mario for his brother Luigi.
