From Bulbapedia, the community-driven Pokémon encyclopedia.
Bluk Berry (Japanese: ブリーのみ Burī Fruit) is a type of Berry introduced in Generation III.
Growth and harvest
A Bluk Berry will mature from a planted seed to a full-grown, fruit-bearing tree in 4 hours, with 1 hour per stage. A Bluk tree will yield 3-6 Berries.
A Bluk Berry will mature from a planted seed to a full-grown, fruit-bearing tree in 8 hours, with 2 hours per stage. A Bluk tree will yield 2-10 Berries.
At 100% performance, a Bluk Berry can produce a level 13 (maybe higher) Sweet Poffin when cooking alone.
In the anime
The Bluk Berry played an important role in the episode Now That's Flower Power!. A Contest expert known as Mr. Big uses Bluk Berries in his fireworks displays. However, May's Torchic managed to eat all of his freshly picked Berries, prompting May to search for more. It was also stated in this episode that eating Bluk Berries causes the hair of people and Pokémon to become shinier. Team Rocket overheard this and went in search of some for themselves.
More Bluk Berries were seen in Abigail's Berry basket in Cooking Up a Sweet Story!.
