So, I will shatter these statues nonetheless? You should have told me that. Either way, here goes nothing.
While clapping my hands, my eyes close shut, as inside my stomach I keep gathering chakra. That chakra slowly moves through my body towards my mouth, as it starts changing it's structure. The chakra becomes wet, and heavy. I's nature slowly continues becoming sticky, and moving inside my mouth in a fluid fashion, with the added fire release chakra, it was warm, nastily warm. I did not think too much of it, but it must have given my teacher bad thoughts, he was taught in this as well. Hm....seems like all toad graduates have to get through this.
Looking at the statue as my eyes viciously open, I pull my upper body back, as if I was charging, and I release the oil stick into my mouth, instantly igniting it as it leaves. The statue was hit with a huge amount of force, burning as it the oil stick to it tightly, aiding the flames in a bright color, releasing a very characteristic smell, a lot more noticeable then normal fire. The oil continued aiding the flames, which turned the statue into sheer rubble.
Quite an interesting technique. I believe that it will be very useful in combat, especially with moving targets, as the oil sticks, renders movements more difficult and burns brightly and stupidly hot. Another advantage would have been the fact that it can't be washed away easily with water, and oil, or at least natural oil, burns even if water comes into contact with it, but I don't know if the same physics apply here, correct me if wrong.
Disadvantages would be the fact that it takes more time to travel unlike normal flames, as it is weighted down by the oil. I can't truly think of anything else. Maybe, also the fact that the characteristic aroma will give enemy insights about your toad abilities.
I stand there as I clean my mouth.
