Here's a herd of bongo antelope
The species has a unique patterning of cream, vertical stripes along the back. Even though there's minor differences in the length, width, and straightness of each stripe per individual bongo, the pattern is roughly the same. The two most profile individuals also both have exactly 13 stripes on each of their backs, which is rather specific for wild patterning.
Game limitations prevent each blue streak on our Blue look-alikes from having these minor differences, but these differences don't distract from the idea that the patterning is essentially the same.
