Prepare to be terrified by the exhibits at the Museum of Little Horrors. But make sure you heed the warning: DO NOT TOUCH! For ignoring these instructions can only lead to trouble. Monstrously terrible trouble.

But Mr. Ellis's class don't take instructions as seriously as they should and, after running riot in the museum, the pupils aren't quite feeling themselves. Ashwin is a little sharper of tooth, Michael's a little less visible, even Mr. Ellis seems a little bit hairier and, altogether, they're just a little bit scarier.

Will Mr. Ellis and his fiendish class find a way of lifting the evil curse and learn their lesson?
