Peter is a small anthropomorphic duck. Absolutely the sweetest little guy you could ever hope to meet, very focused on mental health, always checking in on and offering help and helpful items to everyone around him. He quacks rather than speaks, quacking to the rhythm of words just like Blue and her barks, though in this video Peter takes the role of Mailbox and delivers a letter ✉️ 

A cute, ever chipper, comforting presence out to brighten all the moods.
