Spray
A spray is an object in the Pikmin games. It was found out in Pikmin 2 that one of the new plant species that grows berries has special properties if the berry juices are converted to sprays. There are two kinds of sprays, both described here. Berries can be obtained from the Burdgeoning Spiderwort.
Ultra-spicy Spray
Obtained from red berries. This spray is to be used on the Pikmin. When used, the Pikmin temporarily get enhanced strength and speed, and their leaves glow red. This is useful if they are losing a fight or need to hurry at the end of a day. The spray wears off in about a few minutes.
Ultra-bitter Spray
Obtained from purple berries. This spray doesn't affect Pikmin, but is intended on enemies anyway. When used, it will turn any enemies in the spray to turn to stone. It will last for only half of a minute, but should be enough time anyway for the enemy to be killed. There is a disadvantage, however, as the enemy will crumble when killed and leave behind nectar or sprays.
Both types of sprays can be made by bringing 10 of the berry needed to Olimar's rocket, which will create a spray from the berries. Sprays can also be found in any places where nectar is, in the form of red or purple nectar drops. Each one in the wild counts as a full spray.
