"In Guitar Hero , the hopo notes were colored slightly differently than regular notes."
"The hopo consists of two hedges in the form of the letter V, which are very high and thick near the angle."
"Driving it up with shouts to the narrow part of the hopo, men secreted there throw their javelins into the affrighted herds, and on the animals rush to the opening presented at the converging hedges, and into the pit, till that is full of a living mass."
