The Breezebuilder ship was an air-borne construction used by the Breezebuilders to sail across the skies to different locations.
The inhabitants of Breeze Harbor and Zephyr has for ages been at war. At some point the Land Blubbers invaded the Breezebuilders' homeworld which had everything running on steam from bon fires, so they could stop every machinery from working. The Breezebuilders needed Spyro to stop the Blubbers' havoc so they could get their ship working to sail to Zephyr to do their counter attack on them.
- Why the Breezebuilders couldn't just fly to Zephyr, as they are bird-creatures, is unknown.
