Before the release of Pokemon Gold & Silver there were rumors about Marill being a mysterious new evolution to Pikachu and Raichu called Pikablu, somehow achievable in Red and Blue. These rumors were nothing more than conjecture by fans due to the lack of information at the time. However, this name actually made it into one of the official Pokemon movie trading cards by Topps. This is despite Marill's actual Japanese name even being mentioned on the official Pokemon website. It was corrected in a later edition of the set, but for a time it only served as fuel for the rumors.
