Walmart offers the Fisher-Price Octonauts Gup-S Polar Exploration Vehicle, model no. BDL93, for $10. Opt for in-store pickup to dodge the $4.97 shipping fee. That's the lowest price we could find by $14. It features lights, music, sounds and phrases, and includes Gup-S, Barnacles in his snow suit, two mini-skis, three interchangeable tools, a narwhal, and an iceberg. Three AAA batteries are required (not included).
