3rd Gen Help On Leafgreen.

Well on LeafGreen, My Victreebel needs Sludge Bomb, the question is, where can I find the TM?

My Victreebel, Knows:

Razor Leaf
Toxic
Stock Pile
Spit Up

I decided I would soon get him Sleep Powder from the Move Maniac.

I don't want him to havr Stock Pile/Spit up anymore, so I basically will let him have, Razor Leaf, Toxic, Sleep Powder and Sludge Bomb.

The main question is, Where can I find Sludge Bomb?

EDIT:Mods, feel free to close this when the thread is answered.

Rocket HQ at Island 5. Basically you need to beat the elite four and finsh up the sevii islands before you can get it.
Credit to Psypokes for the details.

Thanks alot, the sad thing is i was going to use it to beat the E4.

Ok, this thread is soon gonna be closed.
