THIS IS MY FAVOURITE POKEMON-CATCHING ANECDOTE.
It actually was the first time I ever caught a legendary without resetting. I tossed a Pokeball and two Heavy Balls, and caught Lugia on the last. I WAS TRULY AMAZED.
It was almost as impressive as when I caught a Giratina with one - yes, one - toss of a Pokeball. JUST ONE POKEBALL.
But I have little love for Platinum, and that was on my friend's game and not mine, so I hold the Lugia catch much closer to my heart! :'D
