Reverting to his male form, Inala inserted a Prana Bomb—filled with Prana—in the rocket's mouth. The rocket's mouth was part of the Spirit Weapon made using his mouth. Therefore, it could crunch the Prana Bomb and cause the fluid within to spill out.
Its internals were pretty much made out of his digestive system. Hence, the fluid was soon transformed into Prana which was absorbed by the pair of lungs at the back.
Through the nozzle, the two lungs gradually began sucking in the air once Inala activated Internal Inertial Gravity throughout the rocket, concentrating their effects within the lungs.
As Prana continued to surge in the lungs, coupled with Internal Inertial Gravity, space began to expand within, causing more and more air to be absorbed and compressed inside. While this was happening, Inala poured all the filled Prana Bombs and Life Bombs into a giant Prana Bomb.
