Belue Berry is a type of Berry introduced in Generation III. To get it in Generation III, tell the Berry Master's wife the phrase: Super Hustle. She will then give you a Belue Berry. It has an awfully sour taste and takes three days to grow in Generation III and 60 hours to grow in Generation IV. In Generation III, it will give 1-2 berries when planted and in Generation IV it will give you 2-15 berries when planted.
