The search for this Euro Pop Mudkip in german has been giving me a headache for years. I regularly search Local listings, Ebay, contacted some previous sellers & co but had no success yet
(At this point I want to thank @Tapp for his article about the cards Bridging the Gap: The Tale of the "Euro POP" Hoenn Starters (Mudkip, Torchic, Treecko) )
