Background: Everyone is practicing combat. Joe fights with a spear.
Joe readied himself, gripping his spear in preparation for his attempt at the target. He squinted at the innocent looking slab of rock, focusing and gathering his inner energy so that he could accurately attack and pierce it through.
With a cry, he charged forward, then jumped high into the air, aiming his spear.
He completely missed the target.
Instead, he jumped over it and ended up hitting a nearby tree behind, embedding the spear deep into the trunk.
Still being a short ways from the ground, Joe hung from the spear and glared at the rock he was supposed to have hit instead. Then with a sigh, he placed both feet on the trunk and pulled the spear out, flipping gracefully as he did so and landing safely back on the ground.
He was about to return to his starting point when he heard the distinct sound of something cracking. Whirling around to see what it was, he suddenly saw that the tree was leaning backwards from the point where the spear had been and he heard noises of splintering, breaking wood.
Helplessly, he watched the entire tree fell with a huge crash.
There were a few moments of shocked silence.
Over at the starting point, Palmon and Mimi stared at him. "Joe..." Mimi began slowly.
"Tree killer!"
Joe and Mimi both turned towards Palmon, who had a look of disbelief on her face. "You're supposed to be a doctor, and you killed a tree!" she shouted.
Joe winced. "It's not like I was trying to kill it," he responded defensively. "Besides, I was already going to be killing the rock."
"Accidental treeslaughter then? You're still a tree killer!"
Mimi threw up her hands in exasperation. "Okay, enough with that, just go ahead and try again Joe."
