Most of the animals on the island are cold and fearful of Roz, but Pinktail is one of the few who actually warms up to the robot quickly. She empathizes with Roz as the robot isn't exactly equipped to nurture young gosling. Being a mother to several other opossums herself, Pinktail helps by giving Roz a quick crash course on how to be a mom.
Official Description[]
Given the fact that she's birthed and raised multiple litters of baby possums, Pinktail knows a thing or two about motherhood. As soon as she sees Brightbill imprinting on Roz, she swings into action, imparting all sorts of parental wisdom on the robot.[1]
