Pua is Moana’s loyal pet pig with puppy energy and an innocent puppy brain."
Pua's name is derived from the word "puaka", which refers to "pig" and "pork" in some Polynesian languages.
As seen in the marketing campaign and early footage, Pua was originally going to join Moana on her adventure. As the story developed, however, he was cut, and instead remained on Motunui as Moana journeyed off.
Pua was originally going to appear in the third installment of Disney INFINITY as a mount. This never saw fruition, as the series was cancelled before the Moana playset was released.
