This egg was given out for Creature Release Week in January of 2014.
Finding a Zebbit egg is a rare occurrence. Most are kept safe within a Zebbit herd who guard their eggs against all comers. So those who wish to raise a Zebbit must search for eggs that have been for whatever reason abandoned by the herd.
Zebbits make their home at the boundary of the Eastern Jungles and the grasslands beyond where they roam over large territories. Zebbits travel in large herds as a safety precaution against predators like Chimeras and Sherths who find Zebbits to be delicious. Zebbits are highly free spirited, even when raised from the egg by a caretaker. As such don't expect your Zebbit to follow any orders you give it, its best to let them roam as they please.
