His arms swung out wildly as he arched his back and pumped his legs to regain his balance - the left leg flexing to lower the center of gravity and the right leg extending straight out into space.

He jackknifed his body hard at the waist to change his center of gravity and reached out wildly with his right hand, grabbing onto a small bush just above his shoulder. He was already tumbling down the side of the gully before he realized the pain caused by the four 2-inch long thorns that skewered his right palm. He hadn't even known he was injured or consciously decided to let go of the bush. He only realized these things when he landed at the bottom of the gully with a loud thump.
