OK so Splinter aka Yoshi Hamato is a father in the new cartoon, however i went to wikipedia and found that in the first NES game, April is Splinter's child, and it's not some fan's prank, the official famicom "Geki Kame Ninja Den" book states that April is his dauther (it got "Musume" (dauther) in kanji)
Now does Nick liked that idea, or it's a coindence? Or maybe Splinter will adopt April too?
