"Yosh, let's try it out ..."
*I close my eyes once again, this time visualizing a larger snake. While molding my chakra, I imagine a giant, 100 meter long snake -- one who's size could easily dwarf some buildings. I firmly root the image in my mind, before imagining myself as if I was in the middle of a battle. I (mentally) place myself in a position where I need to call the snake forth for help. Doing things like this helps me to create a sense of 'urgency,' allowing me to call forth this snake without making a mistake. Once I've kneaded a large enough amount of chakra, I open my eyes once more and slam my hand down on the ground. I release all of the gathered chakra to call forth the snake as if my life depended on it. In a large poof of smoke, the snake appears beneath me, lifting me into the air as I stand on his head.*
"Uwah, you're huge!"
*screams down at you..*
"Sensei, I did it!! What should I do now?"
