In an issue of Nintendo Power UK they mention a Koopa called Clawdia Koopa. She was The Koopalings mother. Then some weird incongruence came with Bowser Jr. appearance Then in a September 2012 interview, Shigeru Miyamoto stated that the Koopalings were NO LONGER considered by Nintendo to be Bowser's children, rendering their maternal parentage a moot point; he also asserted that Bowser Jr,'s mother was simply "unknown" Also all of them look VERY different from each other, Bower might just fucked a lot of Female Koopas and those lil bastards came from them. Or probably Bowser just adopted them. And Bowser Jr.... Heck if i know. But if this was the case... God damn, Bowser. I guess your days of spending a fortune in a Koopa Army and kidnaping Peach are over because of the evil, ancient and dark curse of... CHILD SUPPORT!
