ALEX Toys Rub a Dub bath toys are designed to turn the chore of bath time into the joy of play time. Make music, create art, be a pirate, go fishing or even make soup in the tub--It’s all good clean fun! They’ll be so engaged in playing, they may not want to leave the bathtub! Play music in the tub. Real flutes for the tub are tuned by filling them with varying amounts of water to produce multiple tones. Includes easy-to-follow, waterproof song sheets. Part of the Tub Tunes Collection.
