Beanling

Beanlings are enemies in Mother 3. They are found only in Chapter 1, but are worth a lot of experience points at that point in the game. Another version, the Black Beanling, plays the same high-experience role from Chapter 4 onwards.

Battle Memory description
"The Beanling is a very mysterious creature. It's also quick to run away. If you can catch one, it'll be a great day."
