Which sailor moon season is it from?

I am trying to remember what season this episode of sailor moon is from. i am pretty sure it was the season finale. it had sailor moon and her daughter trying to battle the villain, but sailor moon could not do it with her Millenium crystal, then chibi moon realized she had the crystal from the future inside her. they used both of them to stop the villain and save the day. Please let me know which season it is from
