The Twitch Prime loot will appear inside you Toy Box when redeemed. If you use Twitch Prime, there are some items you can collect for South Park: The Fractured But Whole.

Iron Inventor Costume (Iron Man looking costume) – 20 Club Units.
Currently the available items for purchase are: These items are bought using the club’s Club Units which are acquired by completing tasks in various Ubisoft titles (including South Park: The Fractured But Whole – possible 140 Club Units). If you are signed up for Ubisoft Club, you can purchase a number of items to access in South Park: The Fractured But Whole.
