Piers Petite is a young male bear character and the son in the Petite Bear family, alongside father Patrick, mother Margaret, and sister Andromeda. He sports brown fur and walks upright as an anthropomorphized bear. His most prominent trait is an enormous appetite that constantly drives his actions. Piers frequently declares hunger and abandons playmates mid-activity to chase food aromas. This compulsion proves so overpowering that his mother Margaret excludes him from cooking tasks, knowing he cannot resist touching ingredients.

Within the "Sylvanian Families: Mini Story" anime series, Piers emerges in targeted episodes. His debut occurs in Season 1, Episode 4, "The Great Halloween Adventure!," where costumed trick-or-treaters unravel a mystery. His food-focused persona resurfaces in Season 3, Episode 2, "A Rowdy Day of Pizza Making."

As a collectible figure, Piers features articulated limbs and a posable head. His outfit incorporates Velcro fasteners for dressing changes.
