The "A Goat" skin has NO full body image or Shop display assets, so currently it's very likely to be if you pre-order/purchase "Goat Simulator 3" from the Epic Games store, it releases on November 17th!

It may also be available in the Item Shop later on, but isn't confirmed. https://twitter.com/FN_Assist/status/1575486398890528768
