Pigasi have great fascination with the sky, as their tiny wings can only propel them so far into the air. High-flying pigasi are often the subject of admiration and envy from others of the same species. While the origins of the extraordinary white Pigasi aren't quite known, a lingering theory is that if a Pigasus flies past a certain altitude (whether it be from sheer flapping effort or the propulsion of flatulence), they return to the planet with snow-white skin and shining, golden wings. The most remarkable difference is that they smell like cotton candy. Their fart remains the same, unfortunately. - NEXUS Research Society
