The Project2 website went down around the time Christmas Chronicles was released, so I don’t think anything came out of the XMASBUNNY password. I slightly remember someone telling that the 2 xmas themed Battle levels “Festive Feud” and whatever the other one was called were on there, while those were already included on the disc.

As for TSF’s BUNNYLOVER password, it granted you the easter levels from Project2’s level making competition. All of those were ironically included on the Christmas Chronicles disc as well.

So basically, you don’t miss anything if you have CC.
