The Fisher-Price Shake and Go Bubble Maraca is a two-in-one toy that works as both a no-spill bubble wand and a musical maraca. It helps introduce toddlers to cause-and-effect relationships and encourages early imaginative play. To use, simply shake the maraca to hear a pleasant sound and activate the bubbles—when you stop shaking, the bubbles stop, and you can shake again to start them up once more. The set includes one bubble maraca with an avocado design and a 4-ounce bottle of non-toxic bubble solution. It runs on three AAA batteries, which are not included. To fill the toy, unscrew the bottom and add the bubble solution. For best results and to help the toy last longer, rinse it with water after each use. This bubble toy is specially designed for children 18 months and older, with a non-toxic formula that is safe for babies and toddlers.
