The Fisher-Price Laugh & Learn 4-in-1 Snack Cart Walker is a multi-functional activity toy for infants and toddlers. It converts between four play modes: a sit-and-play center, a walk-behind cart, a push-along walker, and a standalone activity table. The cart features over 30 songs, sounds, and phrases that introduce numbers, colors, shapes, and first words. It includes interactive elements such as a shape sorter, light-up buttons, and a pretend snack tray with removable food pieces. The walker has a wide wheelbase for stability and an adjustable handle to accommodate growing children. Recommended for ages 6-36 months, it requires 3 AA batteries (not included). The product measures 22.5 x 18.5 x 17.5 inches when assembled.
