My First Blender: This children's kitchen accessory is with lights and sound effects, making the toy more vivid and realistic to play with. Kids blender is designed for children who like to pretend to play with kitchen toys, just turn on the switch button, the machine begins to stir with sound. This toy blender can simulate the real juicing and stirring scene, so that children really feel the fun of juicing, while adults can enhance the relationship with children, so that children grow up with fun and happiness. This toy requires 2 AA batteries, which are NOT included.
