I have not found that it makes a difference which item goes in which box because it seems to have changed recently. You don't only make it with red tiger. I've made it with other tiger skins. If you end up with the wrong color you can always put it in with something of the color you want, a shirt or hat or something, and redo it until it changes to that color. Always make sure to have enough coins to undo what you made in case you don't like the results.
