The Koppaites

Koppaites are the dominant species on Koppai. They stand around the size of a nickel, the same general size as a Hocotatian. Unlike Hocotatians, however, Koppaites seem to grow more hair on their heads and have smaller noses. Their eyes appear to be wide open at all times, whereas a Hocotatian's eyes appear small, squinted, and black normally, and widen when startled. Koppaites also have smaller ears that are rounded at the ends, as opposed to the Hocotatians' broader, pointed ones.

Koppaites can breathe oxygen, unlike Hocotatians. However, they must still wear protective suits while on PNF-404 because the planet's oxygen levels are three times higher than Koppai's.

Koppaites are only capable of metabolizing a substance called Piktamin U. It is explained by Brittany that Pikpik Carrots do not contain Piktamin U, which is why Hocotate Freight could not help with Koppai's food crisis. Fortunately, the massive fruits found on PNF-404 contain large amounts of this substance.

One of Alph's dialogues seems to indicate that the Koppaite brain does not produce the hunger-appeasing hormone leptin, meaning Koppaites can and will continuously eat without ever feeling full; this problem was one of the reasons they have fallen into a famine.

It is possible, though not confirmed, that Koppaites might be a related species to Hocotatians, but adapted to a different environment.
