From the Super Mario Wiki
Skolar is one of the seven Star Spirits in the game Paper Mario. As his name implies, as most scholars, he is always studying. He has a brown mustache and wears glasses.
Skolar is the Star Spirit Tubba Blubba once guarded. However, the Star Spirit escaped from Tubba Blubba's Castle. While searching for a way out of the Forever Forest, he was captured by the Boos of Boo Mansion, led by Lady Bow. Bow promised to set Skolar free after Mario and his friends defeated Tubba Blubba.
In Mario Party 5, Skolar is the guide of Super Duel Mode.
