buetifly and dustox
Cascoon evolves into Dustox.
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.
Horsea and Cascoon are extremely rare, but Horsea can be found on Misty's map, Drake's map, Wallace's map, and the Underwater map. But you can only get it like 1/100 chance, maybe even less. Cascoon, you have to get a Wurmple and hope with all your strength that it will be a Cascoon. Usually it is a Silcoon, but you can still get it hopefully. *Edit* Ermm... Horsea and Cascoon are really common and its not a 1% Chance -New009
Cascoon is a Bug type pokemon.
Wurmple evolves into either Cascoon or Silcoon at random. Then Cascoon and Silcoon evolve into Dustox and Beautifly respectively.
You can find Cascoon in the forests of Generation 3 and 4 games. Cascoon wasn't available before Generation 3.
in pokemon diamond a cascoon evolves at lvl 27
Cascoon evolves into Dustox at level 10
To evolve a cascoon, it must gain levels. To gain a level with a cascoon, either attack with it, or if impossible, place it as your active pokemon and switch out at the start of the battle. If you have a EXP share, give the cascoon that and battle with a different pokemon.
A easy way to train Your Cascoon is as follows. First out it at the first spot of your party. Then go to a place with strong Pokemon. Send out your Cascoon then swap it out with your strongest. Defeat the other Pokemon and your Cascoon will get a lot of exp. points.
Obviously cascoon evolve into a dustox because silcoon evolve into a beautiful!!
lv10, Cascoon evolve into Beautifly.
