NHR The Fisher-Price® Train Ball Pit brings this beloved automobile to your own living room. The fun train shape is combined with built-in features that set it apart from a typical ball pit. This includes a see-through, crawl-through door at the pilot of this locomotive. There’s also a built-in horn that conductors can squeeze for a sound effect. The included 25 multi-colored play balls add to the ball pit fun. The bright colors and friendly animal graphics make this train ball pit a perfect addition to any play area or birthday party.
