To get more experience points, near the middle of the first disc there should be a place near woodlands where you will fight a single yellow bird. If you get lucky, it will appear every turn or other turn. It does a good amount of damage considering you are on the first disc. Don't get surprised when you do 0 or 1 points as damage to it.....this is normal! If you are lucky it will stay in with you four or five rounds giving you a chance to defeat it. If not it will run away and you must try again. If you happen to defeat it, you get around 300 experience points which is a good amount during the beginning of the game.
