Beans are collectible items that have made an appearance in five games to date. Additionally, the Beanish are a race of bean-like people.
Mario & Luigi: Superstar Saga
Beans are plentiful in this game, and while collecting them is entirely optional (and time-consuming), they will help Mario and Luigi. There are four kinds of beans in the game, and each is acquired in a different way.
All beans can be taken to the Starbeans Cafe, where they are blended into stat-boosting Bean Juice for Mario and Luigi.
Mario & Luigi: Partners in Time
In this game, Beans are dug up by Baby Mario and Baby Luigi. These can be traded to Fawful in his shop, Fawful's Bean 'n' Badge, for Badges. The Beans in this game bear a resemblance to Hee Beans, although they are never actually given any name other than "Bean".
Mario & Luigi: Bowser's Inside Story
Mario & Luigi collect beans that will boost stats. These beans are called Heart Beans (which add 1 point to the player's HP), Special Beans (which add one point to the player's SP), and Power Beans (which adds a point to the player's attack power). An oversized Bean appears as a healing item for Crawfuls, and also an attack by Magifoofa.
If the player pauses the game, they can access a list of beans that they have collected. The list also shows how many beans are in an area. There are 251 beans in the whole game:
Mario & Luigi: Dream Team
Like in other Mario & Luigi games, beans are a collectible in this game, to the extent they were in Mario & Luigi: Bowser's Inside Story, where they boosted the brothers' stats upon eating them. Beans are marked as Xs in the ground, and upon Mario digging one up gives the player a bean that permanently boosts one of the brother's stats by one stat point. Unlike the earlier games, there are Beans for all of the stats rather than just beans for Power, HP and SP (which was changed back to BP as of this game).
Beans are only dug up in the Real World. If the player pauses the game and goes into the Beans section in the Collection Menu, they can find a list of all the areas with beans and how many they've found and how many there are in each area. Stat DX Beans that increase the aforementioned stat by three points can also be obtained from Golden Beanies as a drop and from Kylie Koopa upon completing a Level 3 puzzle within the goal time for the first time. Beans can also be gained from equipping the Wellington Boots/Farmer Boots, which may turn coins into bean drops. There are a total of 143 beans that can be dug up in the game, with there being 24 Heart Beans, 24 Bros. Beans, 24 Power Beans, 24 Defense Beans, 23 Speed Beans, and 24 Stache Beans to find.
Mario & Luigi: Paper Jam
Beans returned in Mario & Luigi: Paper Jam. Like in the previous games, the number of beans collected in each area can be viewed in the menu, this time from the Collection screen. Beans are dug up from X marked spots on the ground and walls, and can be collected with the Trio Drill ability on the overworld.
In addition to this, the Wellington Boots return and cause enemies to drop beans when defeated. The Bad Nabbit mission also gives the player beans after each battle with Nabbit, as well as after completing the quizzes in the game. Finally, the Broozers' barrel throwing attack may sometimes cause one or more beans to appear when countered.
