Why was he making wooden spears you might ask? Simply because after his encounter with the snake and the giant beetle he at least learned one thing, that is to put as much distance between him and what might try to hurt him, since with some distance he has some error margin in any actions he makes contrary to a close quarter fight just like with the snake. So after a few tries and a few trips at the border of the forest to get more fallen branches, he finally got a wooden spear that was kind of perfect "according to him".
