This is a three-way synchronised cooperation ninjutsu between Naruto, Gamatatsu, and Gamakichi. It is an expansion of the Wind Release: Toad Oil Bullet technique. After Naruto enhances Gamatatsu's Toad Oil Bullet with his wind-natured chakra, Gamakichi steps in and uses his Fire Release: Flame Bullet technique to ignite the oil. The wind not only improves the oil's coverage and distance, but also adds power to the flame. Using this technique they were able to knock out the Three-Tails.
