Well, it says on Serebii that no trainer owns the Pokemon Spritzee, however since the game has been recently released and Pokemon sites are still developing, there is a possibility that I might be wrong.
Hopefully, you can say 'I WANT SPRITZEE' as a shout out and hopefully someone will give it to you. xD
Hope I helped. :)
>i think you have a chance of finding one in the battle chateau on route 7. I have Y and have encountered quite a few trainers with Clauncher and Slurpuff/Swirlix. If all else fails the Fairy gym has the final evolution in their gym and you can trade it then breed. - Pokenubz
So... yeah, that's the answer. Thanks Pokenubz.
