Stack and play with the elephant! Fun elephant stacking set made from sustainable materials: stacking tower, electronic rattle, ring chain. 70% of the plastic components are made from bio-based plastic. The fabric rings are made from 100% recycled plush, conserving the Earth's fossil resources. Three plastic rings and two fabric rings in various sizes can be stacked on the tower. Once all are stacked, the elephant rattle can be placed on top. The electronic elephant rattle features a glowing heart button, two handles, and a rattle ring that respond to movement, playing fun phrases, sounds, and music. The tower has a rounded base that makes it wobble, prompting a reaction from the elephant. The different materials and surface textures of the rings enhance the sense of touch. The two fabric rings have a C-shape, allowing them to be connected to form a chain that can be attached to a stroller, for example. There are three sung songs and 20 children's melodies. The child-safe battery compartment and automatic shut-off ensure safety. Demo batteries are included.
