If you saved your game before waking up the 2 snorlax's you can turn off the game and retry capturing them but only under the above condition u can do this.
It will never reapear again you only have one chance.Or if you save the game right befor you battle him you can try it as many times as you want.
a pk ring can make things vanish, reapear make thing cange ,change places and I hiely recomend it
that route near 1 of the snorlaxs on that long bridge area
there are 2 of them
its worse
During telophase.
decide for yourself, they weigh exactly 1014.1 pounds
they are snorlaxs doing breakdancing and if you join in you get 200 rare candys
yes, eg she was anxiously waiting for man to reapear ....
Make it your starter.
no once you've killed it theres no going back
After you beat him he will disappear but if you beat the Pokemon league again he will reapear in the same spot.
