I'm not sure if the lab ray topic includes petpets, so...
What's your favorite outcome of the petpet lab ray? I know that made your old petpets no longer eliable to PPLs, but I missed all the PPL rewards during my years of being inactive. Besides, it's fun to see random colors of petpets you had never known before! And there are also exclusive colors such as 8-bit and chocolate!
Mine was probably a disco rock that made my day. All rock colors have a nice sense of humor
