Fireball Island just got a whole lot bigger. There's just one problem: It's covered with spiders and they have a nasty habit of "popping up" all over the place. Use the caves to get to the peninsula. Navigate the chasm to scoop up valuable spider eggs. Stop for a snapshot on the scenic bridge. But watch out! When Vul-Kar starts rumbling the spiders start jumping! This expansion adds a new location to explore a new kind of treasure to collect and a new hazard: spiders! Spiders are worth negative points at the end of the game. In the center of the chasm is a spring-loaded "spider launcher". Marbles can trigger the launcher sending spiders around the chasm or into a crevasse where they can make their way onto the main island. You'll even send spiders through Vul-Kar with the new Arachnoclysm action card. It even offers a new way to get off the island via a secret submarine. description from the publisher
