The partnership between Kemono Friends and Nissin involves the promotion of their product, Donbei Kitsune Udon. This is done through the use of Silver Fox and Ezo Red Fox characters in advertisements for the product. In the first episode, these characters are seen trying to determine how to consume the udon noodles while also discovering an old pay-per-view TV, inserting money into it, and watching a live-action Nissin Donbei Kitsune Udon commercial from this year.
