Here is my first story, from waaaay back in grade 9. It's not good but I do think it displays some qualities. The teacher commented, "Good use of descriptive words. Well done!" and graded it 18/20 (-1 for late 1 day) so short as it is I guess it fulfilled the requirements of the task.
The Gorilla
He came striding out of the thick dense jungle, his muscular, fur-covered body gleaming in the hot sunlight. He let out a howl of fury as he saw me. His face was contorted with rage as he bared his fang-like teeth. He flexed all the muscles in his body and commenced beating violently on his chest. He then rose to his full eight feet of height, bent his furry head back and bellowed at the top of his huge lungs. His large hands grasped a snake-like vine suspended listlessly in mid-air.
He began to climb to a limb on the dead tree, using only his hands and his feet. He had reached the lowest limb when the old, withering tree collapsed under the simian's great weight. He fell to the ground with a shriek and landed on some green bush which cushioned his fall. He scrambled up and checked his furry body for injuries. As he found none, he grunted and kicked some limbs of the collapsed tree. He then walked slowly away, scratching his head as he went.
