Dark Ball. Though it is found in the movie Celebi- Voice of the Forest , it is unobtainable through Normal Game Play in Pokemon Black Version.
You'll need a Pokemon and a Poke Ball.
To catch a pokemon, you require a Poke ball, which you can buy from a poke mart.
Catch him with the second master ball you get from the guy at the pokemon center at the top after you have traded 50 times
An apricorn turns to a poke ball.
White apricorn turns into a fast ball, black apricorn into a heavy ball, blue apricorn turns to a lure ball, red apricorn turns into a level ball (very useful), green apricorn turns into a friend ball (also very useful), pink apricorn turns into a love ball, yellow apricorn turns into a moon ball (probably the least useful).
you have a special poke ball ( NOT ON THE GAME) which you can buy in toys R us and then connect it to your game then you can put Pokemon into you poke ball from your game and then you it will count how many steps you do and should make you Pokemon in the poke ball fitter (Hope this helps)
I have played Pokemon silver a lot when I was younger beat maybe 40 times and catching legendary Pokemon the easiest? Well I usually would knock the legendary down as low as possibly in hp then I would put him to sleep after that I would use a poke ball not a great ball not an ultra ball but a poke ball. It seems that a poke balls have a higher catch rate on legendary's it doesn't say that but trust me use a poke ball and here is a trick when the poke ball turns left on the catch screen hit A then hit B when it turns to the right then hit A again and this method gives you a better chance on the Pokemon staying in the ball. it would be easyer to use Ginger and use mean look i did it on rioku and got him
