Mighty Tonic is an item that appears in Super Paper Mario.
To use a Mighty Tonic, the player must shake the Wii Remote up and down. Mighty Tonics can double Mario and the other's attack power for up to 30 seconds (it depends on how long the player can shake the Wii Remote). This can be very useful for boss fights or the Pit of 100 Trials. Mighty Tonics can be purchased at Notso's shop for 70 coins.
