On the Obtainable pokemon list it sais chinchou/ lanturn are catchable on the wild / repeatable event but i've done the team aqua / magma quest and didn't get him and i cant find them so far. Also I havent found any post on google or anywhere saying where or if i can catch them on the wild. Most posts about chinchou is about the event and that's it. Could any1 let me know if or where i can catch a wild chinchou or lanturn?

I've searched alot on google but there seems to be conflicting answers so .... i joined team aqua because i wanted chinchou / carvanha, but i got a ponyta... is there any way i can get a chinchou now ? Lanturn was like my fav gen 3 pokemon and i'll be really sad not to be able to get him now.
