Beans are used to make cofee at Starbeans. The coffee is used to
permanently raise your stats
, and they cannot be used in battle. When you make a new blend for the first time, E. Gadd will show up and reward you with an equipable item (more on those later)-The yellow Hoo beans can be earned from minigames only
-The green Woo beans are dropped by most enemies. You'll need a lot, since they are required in all 3 coffee blends that take 2 types of beans.
-The red Chuckle beans can only be dug up from the ground, so keep a watch out for them. There are some that are completely unmarked, you'll need Mini-Mario to sense them. No one expects you to find those ones.
-The brown Hee beans are only obtained from ? blocks. Incredibly RARE, and most are found in invisible ? blocks. There are no clues to find these, you'll just need to use your intuition. Most are bunched up in dead-end rooms that don't seem to do anything. For example,
that one house with the single mushroom in the corner has 3 invisible ? blocks
