Pokémon Black Version and Pokémon White Version - Fishing
Each area has a specific fishing success rate for each rod, for example, 50%. Once the player has the rod ready, the game waits about 3 and a half seconds. Then, at the chance given by the success rate, an exclamation point appears over the player. As soon as that happens, the player must press the A button within the next second to land the Pokémon, or the Pokémon will get away. The fishing attempt will also fail if the player presses the A button too soon while fishing. If the first Pokémon in the party isn’t an Egg and has Sticky Hold or Suction Cups, the fishing success rate is doubled.
