Feeling Fine

Feeling Fine is a badge in Paper Mario and Paper Mario: The Thousand-Year Door. In Paper Mario, it can be bought from Merlow at Shooting Star Summit for five Star Pieces. In Paper Mario: The Thousand-Year Door, it can be found in the X-Naut Fortress, inside of a giant crane game that can only be used after returning the Cog to the crane. If Mario is equipped with the badge, he becomes immune to a variety of status effects, including Allergic, Poison, Dizzy, Sleep, Electrified, and others. A variant of the badge called Feeling Fine P has the same effect, but works exclusively on Mario's partner.

Merluvlee's predictions in Paper Mario

 * "I see...a Feeling Fine Badge. There is a child upstairs in the fortune-teller's house on Shooting Star Summit. Hey! I'm that fortune-teller! Anyway, the child is my brother, Merlow. He will trade Star Pieces for Badges. Head upstairs to see him!"
