Traversing the Forest: Repost

Narah had successfully passed Pallet Town and made it to Viridian forest. He knew that he had gotten a Charmander and decided to battle with Sally first. He had chucked Sally's ball out and sent her out to Headbutt a small tree that a pokemon could fall out of.
"Sally! Knock a pokemon out of the tree with Headbutt!"
_____ fell out mad at Sally, and attacked it with (move)

(I copied and pasted XD)

(Lazy -.- Also, please refrain from giving yourself auto encounters. '_____ fell out mad at Sally' is an example of auto encountering. It could be possible that nothing fell out at all. Also, you cannot determine that it will immediately attack. The possibility remains, yes, but it could attempt to flee or be asleep or whatever.)

Nothing fell, disappointingly, except a few leaves which fluttered to the ground. Maybe the vegetation around would yield better fruit.

Narah decided to wander around in the tall grass, move like a ninja, and try not to fight a pokemon. He hit a rock and slipped and hit something yellow. It didn't look like a Weedle or Pikachu line pokemon. It wasn't the boot of a trainer. It was very odd.

It was another rock. A queerly shaped rock, with dips and cracks eroded away. It had a smooth surface, though, and almost egg shaped. Strange, how it managed to stand upright. it did teeter around like crazy, but never fell over on its side. Close to it lay a second rock. This one, however, looked normal. Grey, craggy and rough.
