‘Course Not

But then 1 day ‘Course Not couldn’t race anymo’–not due to a busted hoof, but bacteria in its eyelids. ‘Cause o’ this, ‘Course not’s sponsor, Wasabi Woods, would lose many ₧–₧ that may be useful for buying weapons that could’ve ended the war ‘tween it & Worcestershire Woods promptly.

As soon as Orval had found out, he raced himself & his assistants to investigate.

But not only did they discover nothing a few days ‘pon returning to their lab, 1 o’ the assistants caught a terribly debilitating disease:

Trachoma.

Prompt:

Activity, Horse, Trachoma
