I'll be myself. My lines (just to not fail):
-Huh, you think i'm too small for saving the world of minecraft? I can kill...
-You are dead. Just like my teacher when she put me in detention...
-I'm not a hooligan. You are DEAD!!!!
-Oooh! redstone!
Sidenotes: My model is a "chibi" (bigger head, smaller size) I'm 12. so that's why i made first line.
