Re: Advice on catching Snorlax just outside Celadon City in FireRed?
Use strong moves until it looks like the thing has about 50 hp. Your moves should be strong enough that you can get it down to that many hp in 2 turns, in case it uses rest.
Once you're down to around that many hp use dragon-rage. If it looks like there's too much hp use a weak move like twister. Paralyzing it will help if you think you can do it before it rests. Spam great balls until it uses rest or you catch it. If it rests, start over again.
You should save before you try to catch it just in case something goes wrong.
