Invisible Man's Socks

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?
