Vullaby isn’t a good hunter, so it can’t stray from its nest for long. It doesn’t recognize danger and wanders off if it sees anything interesting. When it inevitably becomes lost, it makes a cry similar to Cubone’s to attract its mother.

Mandibuzz only uses the finest bones to make its nest. If the bones get dirty or cracked, they toss the whole nest out and rebuild from scratch. Some towns leave out trays of polished bones after their meal is finished to keep Mandibuzz satisfied.
