Are you ready for the fright of a lifetime? Jodie and Johnny have been invited to Grizzlemyst Castle by their Uncle Barnaby but when they arrive Barnaby's nowhere to be seen. Instead a message from their uncle tells the children that there are many paths through Grizzlemyst but only one that leads to him and a safe way out. You can help the children choose a path and join in their adventure. But beware! Whichever path you choose you'll meet the most amazing horror. The castle is home to hundreds of monsters who have leapt from Leo Hartas' imagination onto the page in this triumph of pictorial storytelling. And there's a wonderful secret to be uncovered when you find Uncle Barnaby and reach the end of the game.
