For 2 to 4 players<p>One of Mattel's most popular games just got even more exciting, with two levels of play. Larger than the classic version, Super Ker Plunk! has a second level of marbles, a see through spiral track, plus fun lights and sounds. So go ahead and take your pick. Try to grab a stick without making the marbles fall. Requires 2 "AA" alkaline batteries (not included).
