"Mmm! Man, who knew there was so many tasty things in this place!" Luffy said happily, licking lips as he patted his stomach. Of course this good mood only lasted a short time before his head was pressing up against the ceiling of the warehouse once again! Even sitting down his head was threatening to break through the ceiling!
"Crap! Stupid powder!" He muttered to himself, sliding his body down lower, propping himself up on his elbows as his large toes started to get scrunched up against the opposite wall. Thinking fast, Luffy shoved his left leg out the door, giving him a little more room to stretch out, his right knee smashing into the ceiling, denting it, his right foot getting uncomfortably squished against the wall. Flexing his toes, Luffy managed to rip just enough of the wall out to allow his toes more room, the thickly swelling digits widening them by the second as Luffy continued to grow more and more.
While he was concentrating on that, he unconsciously tried to sit up in a more comfortable position and smacked his head, hard, against the ceiling, denting it quite severely. The giant rubber man gripped his head in pain, before glaring up at the ceiling. "Why you...!"
Luffy pulled back his arm as best he could before launching it at the ceiling. The horrible shriek of twisting metal filled the air as Luffy's massive fist punched a hole through the roof. Luffy blinked, his anger dissipating in his surprise. It seemed he was now strong enough, thanks to his much larger (and still growing) size, to break down the warehouse! With a mischievous grin, Luffy began to rain blows all around him, fists, elbows, feet, knees and anything part of his body that he could.
To the people of the quiet town it was as if a ferocious hurricane was blasting inside the warehouse, the metal walls bulging out all over, massive limbs appearing and disappearing as an enormous something laid waste to the storage facility. Suddenly, a massive man burst through the roof of the building, showering the area with chunks of twisted metal. The man's arms were in the air, clenched into fists, his back arched slightly with his face turned up towards the bright sun. "Aaaah! That feels so much better!" His voice, while childish still, was deeper and more intimidating, though his easy going smile helped alleviate some of the people's fears. Unfortunately, it wasn't enough. Screams erupted all around the town as people began to run, eager to get as far away from this mysterious naked giant as quickly as they could.
Luffy, meanwhile, scratched his head, tilting it as he watched everyone panic. "Huh...Wonder what they're problem is?" He shrugged and put his hands on his hips, looking around. From his new vantage point he could easily see the Thousand Sunny. He giggled slightly as he realized he was probably way too big to fit on it. "Franky's going to have to really put in some over time to build up the ship!"
With a casual kick, Luffy knocked down the wall in front of him (which reached to about his knees) and stepped out onto the road, walking back towards the town. His every step made the ground shake which only increased the fear of the general populace. Luffy, dense as usual and not noticing that he was the cause of all this turmoil, casually put his arms behind his head and strolled about. "Hmm...now what should I do?"
