A varactyl egg
The reptavian Varactyl species, which are non-sentient, laid large, scale-covered eggs that were golden: these were Varactyl eggs. These eggs were produced in clutches containing multiple eggs. However, even when separated from their family, they could still survive if given the right care. A Human Hunter, Zaina, possessed a Varactyl egg around 9 ABY. She would sometimes bring this single egg with her into the Grand Arena located on the planet Vespaara to participate in the Hunters of the Outer Rim competition, promising to one day return it to its home.
The competitive video game Star Wars: Hunters marked the first canonically appearance of Varactyl eggs. Prior to this, they were mentioned in the description for the Decorative Varactyl Egg Nog drink, which was introduced during the Life Day events in the 2003 Star Wars Galaxies: An Empire Divided MMORPG.
