Petalburg Woods.
You get cascoon when you press the 'B' button on your DS system when your wurmple is about to evolve. The next time it evolves it will be a cascoon. You can not catch cascoon you must evolve it.
You can find Cascoon in Pokemon Platinum at Route 205 North, Eterna Forest.
you catch a wurmple or cascoon and then get is to a level 10 and it will evolve
cascoon knows harden if you catch it, however if you raise a wurple it will know tackle. the reason however is because it is like a metapod.
You cannot, you must get a Cascoon from Petalburg Woods and evolve it.
You have to evolve a cascoon in order to get a Dustox. Either catch one in the wild, or evovle a Wurmple and pray it will turn into a cascoon. It'll be fairly quick, it evolves at level 10.
It evolves into Silcoon or Cascoon at lv.7 like Caterpie and Weedle. It's best to catch a Wurmple rather than a Silcoon or Cascoon because they only have harden. Then at level ten, if you have a Silcoon it will evolve into Beautifly, if you have a Cascoon you'll get a Dustox.Wurmple evolves at level 7 into a silcoon or cascoon.7 (What it evolves into is a random value chosen after you catch the wurmple.)Level 7 randomly it will evolve to cascoon or silcoon you never know!well accually if it's a girl it evolves into beautifly. if boy it evolves into dustox. that's what i believe but i could be wrong.

51 and 52 are Cascoon and Dustox. Wurmple can evolve into Silcoon (thus into Beautifly) or Cascoon, and then into Dustox. It's set for each Wurmple, but there's no way to tell til it evolves. Catch a bunch of Wurmple, and evolve them. One's bound to become a Cascoon.
Cascoon evolves into Dustox.
If you have a cascoon, go to step 3. If you don't, continue with step 1. 1. Catch a wurmple in eterna forest. 2. Level it up, and it should evolve into silcoon or cascoon. If it evolves into silcoon, catch another wurmple and repeat step 1. 3. Once you have a cascoon, give it an exp. share (if you have one) and level up. I f you don't have an exp. share, put the cascoon first in your party and switch it out as soon as the battle starts. 4. Once you have leveled it up, it will evolve into dustox. If you want beautifly, do the same thing, but with silcoon.
Catch a female wurmple Or if you have Pokemon ruby (gameboy game) then just plug that in to your DS when you play Pokemon platinum. Go to route 205 Eterna Forest and cascoon will have an increased chance of appearing.
