Toxic Ninja Art: Explosive Corrosive Bubbles (有毒・爆発腐食性泡, Yuudoku Ninpo: Bakuhatsu Fushoku-sei Awa) is a long-range supplementary technique where, after blowing dozens of bubbles and sending them toward their targets, they are violently popped. Bright flashes of purple light accompany strong explosions which knock back the enemy and everything in the immediate vacinity. The explosions also produce plumes of acid smoke, which can cause the melting of ninja tools and fabrics.
