There’s a nice Moana easter egg in Raya and the Last Dragon
You can check out the details for the Moana easter egg below.
So it seems like Hei Hei the chicken makes a cameo in Raya and the Last Dragon particularly when Raya and her gang reaches Talon. This is also the place where they encounter Noy and her three monkey companions who.steal the gem from Raya.
Hei Hei is the crazy and spaced out chicken from Moana which unwittingly joins Moana and Maui on their quest to get back the Heart of Te Fiti.
