I know what Yellow did for that sequence, that was why what happened threw me off. But I guess I can work with your logic there.
and no, I hadnt found a third gen jessie and james sprite sheet which is odd as almost every game that uses them as characters had used custom 3rd gen jessie and james sprites...you'd think there'd be one on google images all things considered. The closest I came was a 5th gen sprite sheet which would look wierd compared to the other overworld sprites.
EDIT: Wait! I found a decent set! Finally! It doesnt look third gen quality, they look 4th gen which may look out of place right now but it oughta be perfect when you update all sprites and maps in future updates after you get back from vacation.
