Money Money

Money Money is a badge in Paper Mario and Paper Mario: The Thousand-Year Door. In Paper Mario, it can be bought from Merlow for twenty Star Pieces. In Paper Mario: The Thousand-Year Door, it can be bought from the Pianta Parlor for 234 Pianta Tokens and can be rarely dropped by Dark Boos, Bill Blasters, and Bombshell Bill Blasters. If Mario equips the badge, he gets more coins after a battle, though the exact amount depends; in Paper Mario, he gets exactly double what he would have normally obtained, while in Paper Mario: The Thousand-Year Door, the number of coins he obtains varies from being slightly less to slightly more coins, which can be augmented by equipping more copies of the badge.

Merluvlee's prediction in Paper Mario

 * "I see...a Money Money 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!"
