Pop Green

Pop Green (ポップグリーン) is the seed of the hostile plants in the forest of "Greenstone" on Boin Archipelago. It can grow from seeds to full-sized plants in moments.

History
Heracles uses these seeds as bullets and weapons. According to Heracles, they have various uses. Heracles taught Usopp how they work.

Usage
Not much is known about the Pop Green's usage, but it can be used to create plants. How it is triggered is currently unknown. Usopp fires them with his new Black Kabuto and it summons a carnivorous plant to attack the target on impact. Also, despite each seed looking the same, Usopp seems to know what each one is capable of.

Usopp's Attacks
After two years of training with Heracles, Usopp has gained mastery of a new type of powerful weapon: the Pop Green. They are seeds of hostile plants that can grow at an incredible rate. According to Heracles, these seeds have various uses, especially in combat. The following is a list with the different applications Usopp gives to them:




 * Midori Boshi: Devil (緑星・デビル): Shooting Pop Greens, Usopp creates a large carnivorous plant (that vaguely resembles a Venus Flytrap) which attacks his enemies. In addition to being able to eat enemies with its large mouth, it can ensnare those nearby with its vines. This was first seen used against Demalo Black and the fake versions of Franky, Nami and Sogeking for harassing the real Nami.


 * Midori Boshi: Sargasso (緑星・サルガッソ): Usopp fires a pop green at his target, which then explodes into an array of strong, resilient seaweed, strong enough to delay an avalanche of rock and earth. The name of this attack comes from the Sargasso Sea, a region of the north Atlantic Ocean where ships often become tangled in weeds.




 * Midori Boshi: Rafflesia (緑星・ラフレシア): Usopp fires a Pop Green at his enemy, not aiming for them specifically but a place near them. The pop green reveals a rather large Rafflesia flower. The flower then excretes a foul smelling odor, disabling the enemies with its stench. This was first used against Hordy Jones and his men. The odor is strong enough for Hordy himself to cover his nose, commenting on its childishness.
