Part Too You had your heart set on legging it through the neighborhood as Disney's Ariel for your kiddo's first trick-or-treat. It didn't matter if they wanted to be a superhero, witch, or dino, you were going to don the flaming red hair and mermaid costume. But as your excitement for October 31 grew, it bubbled and spilled out for everyone to see. Your toddler decided then and there, they wanted to be a part of the world you were creating too! And if you were going to make a splash on Halloween as Ariel, it only made sense for your kiddo to take on the role of Ariel's faithful sidekick, Flounder! Fun Details Bring the fun of Disney's The Little Mermaid to your own home when you add this officially licensed Toddler Disney Flounder Costume to your plans! The easy-to-wear costume starts with a simple tunic. From the front of the slip-on look, Flounder's cherub cheeks and perfectly pinchable nose take shape with fiber filling and embroidered facial features. Lightweight foam fins, a tail, and hair are attached to the costume to ensure the vibrant yellow and blue fish looks like a fish. Spacious openings at the arms and bottom make layering the necessary clothing easy and hook-and-loop fasteners keep the costume at the back.
