go to diglett cave
Well, if I where you I would use it on Mewtwo in Cerulean cave after beating the Elite Four when the guard is not there, another good call is to save it and if you get any event Pokemon use it there
It should be in the Cerulean cave
I'm pretty sure that the Rocket Grunt does not immediately show up in the Cerulean Gym. He should be stirring up trouble on the Nugget Bridge (north of the gym). Talk to him there, and he'll battle you. After beating him, he should run away. THEN you should be able to find him in the Cerulean Gym, and there he will give you the part for the Power Plant. (It's been a while, and I played SoulSilver, but in any case this information should be correct)
Sorry but you can't get jigglypuff in Pokemon pearl. You should trade with someone who has soulsilver or heartgold or you can buy soulsilver or heartgold.
You should go and head to Mr. Pokemon's Lab.
no u should buy a heartgold or soulsilver
I mean…do you want Pokemon HeartGold? The difference between HeartGold and SoulSilver is that you catch Lugia in SoulSilver and Ho-Oh in HeartGold. Other than that they’re the same thing. You need a DS, DS Lite, or 3DS to play it though. It’s not playable on any other console.
Route 11 - it should be obvious exactly where...
heart gold
This should help... TM 64 (Explosion) - Buy Ragecandybar at Mahogany, exchange with guy in underground path between Cerulean and Vermillion
After beating u should get the Sapphire Gem. Now go to 1 Island's Pokemon Center. Talk with Celio
If you Poke Transfer from Heart Gold to Black, the Pokemon should be in your box
