Zap Tap

Zap Tap is a badge in Paper Mario and Paper Mario: The Thousand-Year Door. In Paper Mario, it can be bought from Merlow for 10 Star Pieces, and in Paper Mario: The Thousand-Year Door, it can be found in the Pit of 100 Trials (level 30). If equipped, it electrifies Mario, causing any enemy that makes direct contact with him to be damaged.

Merluvlee's prediction in Paper Mario

 * "I see...a Zap Tap 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!"
