Hesperornis [PvE Cross]

The only use for Hesperornis is to get a golden Hesperornis egg, which, when eaten, applies an XP buff and is also one of the possible cravings for Rhyniognatha incubation. To earn a golden egg, you need to order a female Hesperornis to attack a good-quality fish or a good-quality fish's body. Every 5 harvested bodies, it will drop an egg, and every 5th egg will be golden!
Hesperornis eat only fish meat throughout their whole lifespan, and they can be carried around on your shoulder for convenience.
