From the Super Mario Wiki
Kalmar is one of the seven Star Spirits found in Paper Mario. He is the star spirit designated to the Crystal King to guard in his very own Crystal Palace. As his name implies, he is very calm and hates fighting and arguments. His name is also the same as the Swedish city Kalmar, a fact possibly taken into consideration in the game's development when choosing to place him in a very cold area.
In Mario Party 5, Kalmar serves as the guide of the options mode.
These are Kalmar's Paper Mario statistics.
