When a Pokémon with the Gulp Missile ability after using the moves Surf or Dive it catches a prey. If Cramorant’s HP is at 50% or higher, it will come up with an Arrokuda in its mouth. However, if its HP is below 50%, it will surface with a Pikachu instead. Once it has a catch, the Gulp Missile ability is activated. While the Pokémon holds the fish, if it takes damage from an opponent's attack, it retaliates by spitting the catch at the attacker. This spit attack deals 1/4 of opponents max HP as damage and has additional effects dependending on its catch: Pikachu: Paralyzes, Arrokuda: Lowers defense.
