This unique bird whistle from Neato! for kids is shaped just like a tiny bird perched on a solid stand. The bird’s tail is merged into the blower tube. Simply add water and blow into the tube to make a lovely warbling sound. Each bird is intricately designed and measures 2.25 inches. Made of high-quality, durable, nontoxic plastic, the whistle is safe for kids to use and easy to clean.
