When i look up at the spriters resource website of Rookie. They said they will rip the Japanese Versions of Bowser & Rookie. However. It did not Happened. So i decided to rip these better looking rookie by myself. Except for the hammer & Fireballs. Because it looked the same as the american. But don't worry. You can actually recreate some animations using a video or american sprites for a reference.
If you want to use these. Please credit me me if These are used. Enjoy with these sprites.
