“Call on me when times are bad. Believe in this, Mario: My powers are strong... I'm a Star Spirit, after all!♥”
—Mamar, Paper Mario
Mamar is one of the seven Star Spirits in Paper Mario. Because of her kind-hearted and happy nature, she looks after the six other Star Spirits. She is the Star Spirit Tutankoopa guards. Her power is just like a Sleepy Sheep.
In Mario Party 5, Mamar is the guide of bonus mode. She is the only Star Spirit that appears on the box art, shown as a regular star with a bow.

"Advice From The Star Spirits" Entry
Mamar's Hint: Visit Merlon when you don't know what else to do.
Merlon won't tell you exactly what to do, but what he does tell you should be helpful.
"Mario, dear. If you ever get to a point where you simply don't know what to do or where to go, visit Merlon in Toad Town. Merlon is a fortune teller, and I'm sure he can foretell what you are supposed to do. Just remember that it costs money to have your fortune told. There are lots of nice people who will give you good advice, too, so be polite and take the time to talk to everyone you meet."
