1. Put the tray files in your TRAY Folder
2. Put the mods in your MOD folder

When you are in-game, go to your gallery, select families (with custom cc), and then select the Nighfury model in the gallery to play with it, or add it to your current family :)

You NEED the talbuk costume for Nightfury's costume to show up, because it is cloned from the Talbuk. Both packages need to be in your game for it to work.
If you already have the Talbuk pet installed then you can disregard the package that I added in the Mod folder.
