How do you get into Cerulean Cave on Pokemon Leafgreen?

Question

And WHERE is the AIDE with the ITEMFINDER? Please let me know!!! I'm stuck.

Answer 1

You'll need to beat the elite 4 the first time, have gotten the national dex and complete all the islands events on 1-7

Then head back to the Elite 4 and face them again and beat them, then you can go to the Cerulean Cave/Unknown Dungeon.

Answer 2

1. Cerulean Cave
Beat Elite four and use surf to travel to it. Some one will be blocking it if you have not beet it yet. Make sure you have STRONG POKEMON with you when you enter.
Pokemon levels are from 50 to 70. You will find mewtwo not mew.
2 The aide with ITEMFINDER
I am not exactly sure. I have not played the game in a long time. I think I remember you find it at one of those little stops. Its a building. And upstairs you will find the aid. I think thats it.

Answer 3

the cerulean cave is located at the right side of the nugget bridge. go up and when the bridge ends turn right. youll see some grasspatch there and a body of water. surf down there and follow the water's path.

the item finder could be found at route 11. from the diglett's cave just step right until there's a building. go in youll see 2 police. 1 up 1 down. youll see stairs on the lower right corner. go up. go left then youll see prof oak's aide. hell give you the itemfinder if you happen to have 20 or 30 pokemon on your pokedex.

that enough scoop?
