I just was playing Pokemon white, when I ran into a wild Crobat. Excitedly I whittled down its HP and threw a Dusk Ball. Next thing I know there is a pause, a high pitch whoosh, as the Pokeball goes out, sucks in the Pokemon, twitches while in mid air, then falls, rocks once and the Pokemon is caught. This has happened to me twice now. So to all pokeplayers, has this rare occurrence of a super throw happen to you?
That's a random chance, makes it easier to catch the pokemon. There's only one way he could've avoided it.
You get a better chance of a super throw... i don't know, it's either the more pokemon you catch or the more you have recorded in your Pokedex.
