Pet shows/contests

[Dinocanid]

I planned to have some sort of pet show/contest mechanic on my site, but how would I go about it? I wanted to have it so the show would be held on a certain date and the pet with the highest stats in that category would win and get a trophy. (For example, a cuteness contest would pick the pet with the highest cute stat as the winner). I already know how to do stats, but I don't know how to make it so users can enter the contest and the script would check the stats of each entered pet. I could just make the trophies key items that sit in the user's inventory, but I wanted it to show up on their profile.
