There is an old tradition to count sheep to lull oneself to sleep. This tradition has dozed over time, and the sheep were left out of job.
The people forgot that the only thing sheep could do was to induce sleep. Flocks of unemployed sheep began wandering around, putting people to sleep.
To fight them, an army of sheep killers is banding together. Join the sheep fighters and win the right to sleep when you want to, not through the whistle of sheep!
