Double Dip

Double Dip is a badge featured in both  Paper Mario and  Paper Mario: The Thousand-Year Door . The badge is upgraded in the form of the badge Triple Dip.

Paper Mario
In Paper Mario, Double Dip is a very helpful badge. In battle, so long as this badge is equipped, Mario  can use two different items during each of his turns. His partner's, however, cannot use this effect. Double Dip costs 1 BP to wear and to use this attack in battle, Mario must use 3 FP. Double Dip is a great badge for dealing damage as Mario can use multiple attack items like Thunder Rage  and  Shooting Star.  Double Dip can also be used to heal large sums of HP by using multiple healing items, but Mario can unlock this badge's ultimate power by using both a healinng move and an offensive one at the same time. In the game, Double Dip is found once in Paper Mario. Sometime in the middle of the game, Rowf's Badge Shop  will have this badge on for sale. It's cost here is a small fee of 100 coins. This badge DOES NOT allow Mario to use multiple attacks, just multiple items. It does this in both games.

Paper Mario: The Thousand-Year Door
In TTYD, Double Dip is still very helpful. Its purpose remains the same and its usefullness somewhat stays the same. Unfortunately, Double Dip is nerfed in this game. It costs a total of 3 BP to wear and the attack costs 4 FP to use. This makes using this badge a lot worse than in'' Paper Mario. ''Mario can find two different Double Dip badges in the game. The first one I should mention is accessible later in the game as Mario needs the ability to transform into the boat. With this new ability, Mario can go around the river on the eastern side of Rogueport. Here, Mario can find this badge in a treasure chest. The other badge is found in the deep reaches of the Pit of 100 Trials  located in  Rogueport Sewers. In this game, Mario can use this badge to make his own Triple Dip. Since Triple Dip isn't featured in Paper Mario: The Thousand-Year Door, Mario can equip two Double Dip badges to gain the effects of Triple Dip. This does, however, increase the FP use for Triple Dipping. Later on in the game, Mario also can find Badges  named Double Dip P. These badges are used to do the same thing for Mario's partners.
