Brand: Pink Fong size: marked toddler My 16 month old wore this description: Sings! The left fin of the shark has a pink fong musical puck that when the button is pushed, sounds off baby shark song! will need 3 x 1.5 v replacement batteries as our toddler wore it out. we get ours from the dollar store. or just take it out, the costume works fine without it. Soooo cute! Everyone knows the bright yellow baby shark! This costume is a very good quality. Its shape is made sturdy by an inner batting. Outer material is soft. Eye and nose details are embroidery, and shark teeth are felted. Over the head style. Side zipper and three snap crotch. The hood is the shark head. This costume was perfect for our toddler because he refused to wear hats or masks. This costume is all weather friendly because they can wear long or short sleeves. Weather here on Halloween can be either snowing or 80° just kind of depends! Questions? let me know! thanks for checking out my closet
