Ultra-bitter spray

Ultra-bitter spray is the purple colored spray that can be obtained by collecting ten purple Burgeoning Spiderwort berries or by finding a concentrated dose. When used, it temporarily turns any nearby enemy or bomb rock into stone, completely immobilizing them, and rendering them harmless, for a short period until they automatically break free. Flying enemies that are petrified drop to the ground, and may shatter apart upon impact depending on their integrity. Any enemy that becomes petrified will have its defense changed in some way, such that all Pikmins' standard attacks and leaders' punches cause more damage to normal enemies and less damage to bosses. When an enemy is defeated while petrified, it will crumble to dust and leave behind one or more drops of nectar or sprays along with the objects it would normally drop.

In Pikmin SP
In Pikmin SP, ultra-bitter spray can be found in Bramble Woods, behind a black bramble gate, quite close to the landing site. It is gained from purple Burgeoning Spiderwort berries and as spray nectars. The spray has different effects on certain types of enemies, as it keeps normal enemies petrified for ten seconds while boss enemies stay affected for only five seconds. This spray does not affect some enemies at all, but has quite a bit of use against a certain boss

In Pikmin V
In Pikmin V, ultra-bitter spray has been significantly balanced. Instead of petrifying enemies, it merely stuns them the same way that a Purple Pikmin does, and the duration only lasts between three and five seconds, depending on the size of the enemy. While still less common than ultra-spicy spray, it is also more common than the newly-added ultra-tasty and ultra-nasty sprays. Sprays only become available once Brittany has been recovered, and the Burgeoning Spiderworts that produce their berries aren't found until the Forest of Seeming region is entered afterward.

In Pikmin X: Deep Freeze
Ultra-bitter spray appears in Pikmin X: Deep Freeze. While it can still be obtained from purple Burgeoning Spiderwort berries, breaking open eggs or killing Black Spectralids, the spray no longer petrifies enemies; instead, using the ultra-bitter spray causes a circle of gas to form around the leader who used it, acting as a repellent. It has a large range and enemies will refuse to enter its perimeter. Should the leader who used it come too close to an enemy, it will flee and open itself up to attack, protecting Pikmin from them. The effects wear off after about thirty seconds. Bosses and minibosses are immune to the effects of this spray.
