You've got the foxes and boxes, and Alex has the raccoon, because you're not all that tech savvy and they were just what came with the app. Sometimes you go look in other peoples' boxes and you're greeted by a different character, but your guy's the fox for two reasons:
1. All those other characters aren't in the app, the app was made by one guy and the characters and background graphics and all that were made by other guy, and your app will take the character and graphics packs made by other people but you have to go and find them and all that jazz and you just don't have time for it, and
2. You like the pixel fox anyway
