Hape's bath waterfall toy set features a clever suction cup design that transforms the bathtub wall into crashing waves. The flowing water makes the marine animals dance and spin, adding more fun to bath time. Use the water jug to pour water over the set, bringing the animals to life and activating the water slide. The set includes two wave-shaped water slides, three moving marine animal figures, and a water jug. The starfish acts as a water wheel. When water is poured into it, it spins and redistributes the water below. The crab sways side to side while water is poured, distributing water from its claws, making it look like it's dancing. Pour water into the octopus, and it flows out from its tentacles. Children can play with each element individually or combine them to create different waterfall designs. This bath set teaches children about water flow, gravity, and various marine life. Recommended for children 24 months and older.
