The Fisher-Price 4-in-1 Ultimate Learning Bot is a playtime buddy for baby featuring 4 ways to play and lots of fun music, lights and hands-on activities. Each bot has its own fun for little ones to discover, from spinning eyes to silly popping balls to exciting crawl-and-chase play. Baby can play and explore each bot individually or build them up into one big interactive buddy with fresh music, sounds and phrases! And with Smart Stages technology, you can switch up the learning content to best fit your child's age and stage.
