Hibernation Cave



"Sometimes dragons like to be in dark places. Since we're sure that you don't want an angry dragon on your hands we thought that it'd be wise to provide a dark place away from the prying eyes of visitors for some of your dragons. Of course, since visitors can't see them, these dragons will not earn any income while hibernating!"

The Hibernation Cave was added in update 1.5.0 and allows you to store up to 25 dragons within it. Dragons that are stored do not earn income for their habitats. The Hibernation Cave can be bought in the Market for 3,141,592 and can be upgraded for 50 to hold 50 dragons, and 100 to hold 100 dragons.This building can be bought at level 14.

Strategy
Shrines: Dragons can be fed to level 10 and be stored in the Hibernation Cave. Once the shrine you are working on turns silver you can take each dragon out one by one and feed it to level 15 before selling/keeping it. This will help save DragonCash and food while trying to obtain the Gold Shrines.
