help me please!!!!

You need to get a Rainbow Ball to catch a Rainbow Mudkip, whereas a Shadow Ball for a ShadowMudkip. In order to get any of these, you'd need 495 credits to buy them, or use coins, or buy from other players. The perfume is to attract the Pokemon, but if you don't have the Ball, you cannot catch it. Also, you can read more on this if you search the threads. Thanks!

i have shadow ball

Well, you have both balls, so you attempt to catch either one. If you have Shadow Ball, use the Shadow Perfume and go around the pages. The Pokemon will randomly come out and one of the thread states that you have to battle it and use the Shadow Ball to catch it. It doesn't really clarify if it faints can you catch it, but nonetheless, you'll have to look around the pages for the event to come up. Also, you cannot get catch them through battling pages. So if you want RainbowMudkip, use the Rainbow Perfume, and if you want the ShadowMudkip, use the Shadow Perfume. Hope it helps and happy hunting!

which map that appears S.M? some have in common? or it will appear on any map?

I believe they can appear in any map including any pages on the site except the battle page.

"Finally, this pokemon will appear on a random page (except battling) and you will have to battle this pokemon and catch it with a rainbow/shadow pokeball to recieve it."
hope this clarifies it!

thank you

You are welcome, hope you find it because I'm dying to find a RainbowMudkip come out!

In my opinion its not worth it just ask someone who has one for it. it takes ages to get enough credits from the lab and if you spend your coins you lose them all and there's no certain way to get the mudkip it might take ages to find
