Fire Release: Toad Oil Flame Bullet

This is a two-way cooperation ninjutsu used by Jiraiya and Gamabunta.

Usage
Gamabunta uses shoots a jet of oil from his mouth, before Jiraiya spews a blast of fire onto the substance to ignite it, creating a giant flame-thrower effect. The flames were intense enough for Manda to shed his skin to escape it.

While Naruto not knowing Fire Release ninjutsu at the time used this technique, he opted to use explosive tags instead.
