Electro Pop

An Electro Pop is an item that recovers fifteen HP and Electrifies the user. In the Paper Mario series, the candy is made by mixing a Volt Shroom with Cake Mix. An Electro Pop sells anywhere in the world for twenty-five coins. Mixing an Electro Pop with a Dried Bouquet makes Space Food.

Assuming you have the curse minigames and enough Pintas already to use in the minigames (preferaly paper as it is easiest), you can earn Pintas to spend on cake mix (also remember that you must not spend too many Pintas that you go below 10), and buy a Volt Shroom in the nearby shop. Doing so and mixing them together will give you a Electro Pop which you can sell for a 15 coin profit (thats why you are better off starting with enough Pintas).

In Super Paper Mario, they were made by Saffron when given a Thunder Rage. They also made the user electrified, but when the player touched foes, they got shocked.
