Effects
It's only effect was petrifying your enemys with a burst of gases which would envelop your enemy in stone. This would only work on some enemys. In 2 player, it would cause hostile creatures to be encased in stone and enemy Pikmin would be planted in the ground again, and if they had flowers or buds, they would be converted into leaves again.
Creation
It was created by the ship to help Olimar fend off hostile creatures. It was made from bitter tasting berrys which the Pikmin would hoard in the ship.
