The Sludge Bomb move was introduced in the second generation of the pokemon games (Gold, Silver & Crystal). These games were set in the Johto region. So I guess you can say the move is from the Johto region.
in the kanto region.
I think shadow ball would be because it's more powerful, but that's just my opinion. Then agiain, sludge bomb has a chance of poisioning the foe.
There is a move deleter in the kanto region but only in firered and leafgreen not in red blue or yellow, the move deleter is in a house right next to the Pokemon center in fuschia city.
Replace Toxic with another grass move.
Explosion (250 base power). And if you don't want to kamikaze, Sludge Bomb (135 base power).
Yes, you keep the Pokemon from Johto when you get into Kanto, otherwise you wouldn't be able to battle the Elite Four!
Cross Chop is not a TM or a Move Tutor move, so you can't 'aquire' it anywhere.
you will get rock climb once you have all the badges in the kanto region.

no the best are toxic sludge bomb gunkshot and any move for last by dgamer297 :D
The two really good move it will learn on its own are sludge bomb and screech. You can also give it TMs that are ground and poison type.
Victreebel doesn't learn sludge bomb. You have to teach it to it. Victreebel can't actually learn any new moves by leveling up. If you wanted it to learn a move by leveling up, you had to keep it a weepinbell till it learned whatever you wanted. That's what I"m doing. I'm waiting for my weepinbell to learn razorleaf...
