LEGO Friends Sea Rescue Boat - 717 Pieces | Kids who care about the natural world can learn about ocean life with this detailed LEGO Friends Sea Rescue Boat toy building set for ages 7 and up. The set comes with a buildable catamaran that doubles up as a laboratory, plus a small submarine toy. Kids can act out sea rescue stories as they roll the boat over the trash to capture it in the boat’s nets, ready for recycling. Nova and Aliya didn’t think that they had much in common with one another but are becoming closer as they take on this shared mission.
