Berries

Berries are items that can be acquired from leveling up, spinning the Photo Disc at a Gym or PokéStop, or defeating a Raid Boss. They can be used while capturing wild Pokémon and to feed them in Gym.

There are currently four kinds of berries available in gameplay:
 * Razz Berry,
 * Pinap Berry,
 * Nanab Berry
 * and Golden Razz Berry.

Trivia

 * The in-game description of the item is misleading. It states that feeding Razz Berry to a Pokémon "on your next throw" will make it easier to catch. The effect actually lasts until the Pokémon enters a Poké Ball at least once. If the Pokémon seems to be captured, but escapes the ball, the effect of the berry wears off, and another must be used. If the Pokémon does not enter the ball, such as if the player's throw misses, the effect does not disappear.
 * Also only one berry can be used at a time. After an unsuccessful capture (Pokémon escapes from Poké Ball), effect of berry wears off and the player may use another berry.
 * The following berries' name's are based on names of real fruits:
 * Razz Berry is named after raspberry.
 * Nanab Berry is banan(a) spelled backwards.
 * And Pinap Berry is pun of berry and pineapple
