Sewn Multiple Times: Most toys have just one seam to hold the toy together. We sew webbing around the edges of the toy and then sew the edges together to make each toy Tuff. Squeaker Safety Pockets: Squeakers are sewn into pouches as an added layer of safety.These toys are machine washable (air dry) and float.The Zoo Series are not guaranteed due to their detailed construction.
