Dragon Power

Dragon Power (often abbreviated as DP) is a fictional currency that appeared in Mother 3. It first was mentioned in Chapter 2 as simply "money". However, it is not actually used until Chapter 4.

In Mother 3

Dragon Power appeared in Mother 3 as the game's currency. Prior to the events of Chapter 4, no money was used on the Nowhere Islands. It was brought to the people of Tazmily by a suspicious peddler, given to Butch in exchange for his pigs. Butch hid it inside the town well so nobody would steal it. Unfortunately, it was stolen at the end of Chapter 2. It is soon found out in Chapter 3 that Fassad had stolen it not so long after Butch had hidden it. Duster is blamed for the robbery due to the fact that, to Butch's knowledge, he was the only one who knew where he had hid the money. Dragon Power reappears in Chapter 4, where its name is actually dubbed "Dragon Power". The player can withdraw or deposit DP from Save Frogs from that point on. DP can then be received by defeating enemies like in the previous games. The money won from enemies will be added to the money saved with the Save Frogs. It is unknown where the name "Dragon Power" comes from, what it is made of, or what it looks like. The name may have come from the Dark Dragon.

Trivia

In some Yu-Gi-Oh video games, DP is used as a currency. However, in these games, it stands for Duelist Points as opposed to Dragon Power.
