Glitz Pit Security
From the Super Mario Wiki
The Glitz Pit Security are the security of the Glitz Pit that watch over certain areas of the pit in Paper Mario: The Thousand-Year Door. The species of the Security is unknown, but are all blue skinned. The security's purpose is to work for Grubba (later Jolene) and make sure the fighters don't get out of hand. However, before the championship fight, one of the security members leads Mario to a deserted locker room and locks him inside, minutes before the fight. This leads to the conclusion that Rawk Hawk cheated and somehow convinced the security to lock Mario in and prevent him from fighting in the Championship match.
