The cross breed between a piranha and a trout, found mainly in regions of the Arkansas River in Colorado. They are extremely ferocious and upon meeting a prout, one's life may be in danger.

Characterized mainly by large frontal teeth and swimming upstream.
The Prout were swimming so far upstream, when the boy scouts in my raft fell out I had to reach in and save them quickly, so they wouldn't die by the prout's enormous frontal teeth.
