These are the two short Try! Try! Try! webcomics included on the bonus CD that accompanied Azumanga Two. They were assigned silly episode numbers to indicate that they are merely small bonus installments. The first, Episode -1: Ena-chan's mishap, recounts an interesting discovery made by Ayase Ena. The second, Try! Try! Try! Fractional Episode, is a pleasant story depicting the various characters' reactions to Yotsuba's mischief.
