A Bluk Berry 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 used 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.
The bag description for a Bluk Berry in Pokémon Omega Ruby and Alpha Sapphire state that the Berry is sour. The original Japanese description describes it as 渋い, which was previously translated as dry in the Generation III and IV games.
