Skully may just be one of my most successful classroom implementations ever. This part scary, part rhythmic all fear inducing shaker defines classical psychology. It only took a single class to pare the cue, beads shaking, with a negative stimulus such as reduced game time, loss of Super Student Stars and sometimes both.
When Skully shakes silence blankets the room... at least for a good twenty seconds or so :)
ps. Came across this little guy on the sidewalk today.
