Power up an epic head-to-head battle with the LEGO Pokémon SMART Play: Charizard vs. Jolteon Ultimate Battle (72167) set, an interactive LEGO building toy that reacts to how kids move and play. Part of a collection of sets powered by the LEGO SMART Play system, this All-In-One Set includes 2 SMART Bricks, a SMART Charger and 4 SMART Tags – everything kids need for responsive Pokémon battle adventures with dynamic lights and sounds. When the 2 SMART Bricks are added to the Charizard and Jolteon figures, they will react with different sounds, lights and other interactions as they sense each SMART Tag and respond to kids' movements. For example, certain movements will cause the SMART Bricks to react as if they are getting stronger while combined with the Pokémon figures, and bringing them near the SMART Tags can initiate a battle or a reaction to the healing spray. Combine this building toy with LEGO SMART Play Compatible Sets (each set sold separately) to expand the interactive play possibilities with even more Pokémon figures and stories. Use the LEGO SMART Assist App to help kids get started, troubleshoot, control sound levels and download updates for enhanced SMART Play action. Take kids to a world of open-ended, imaginative fun with this unique gaming gift for boys, girls and Pokémon fans ages 8 years old and up. Contains 751 pieces, including 2 SMART Bricks.
