So, a meowth and a mudkip walked into a bar. They consumed much fermented berry juice, and they decided they loved each other very much. Poor decisions were made, and the next morning, there was an egg. They assumed that it would hatch to be a mudkip, like the mother, so they just pretended it had magically "appeared" like the old man at the Pokemon Daycare center does. They took the egg out in a field, when right before it hatched, it was hit by a magical rainbow. The egg hatched, and it was neither meowth nor mudkip, but Meowthkip, a brand new pokemon defying all laws of pokemon biology. And while the rainbow had created this new pokemon, it also made him a total fag, as it was the same rainbow that transformed the wild Pikachu into Sonichu, who is pretty much a closet case anyway.

And thus, the humble beginnings of Meowthkip.
