Definitely, since I've never bred one in 4th generation that should be fine. :) When you're ready just make your request. If you don't care about nature/ability/etc that's fine (IVs too), I'll just do what is best competitively and you'll get a shiny Piplup that dominates! :)))))))))))
So, basically just use the form and ask me to breed a Piplup, Shiny yes, then say Doesn't matter on everything else. :)
