This is a rare resource to upgrade the habitats in your Zoo.
You need to upgrade your habitats to increase the maximum capacity of the Energy to have even more adventures.
Each habitat can be upgraded only once. To be upgraded a habitat must have at least two animals settled. And be careful, if you move the upgraded habitat or one of the animals to the warehouse you will lose the upgrade.
You can get Magic Dust as a reward for completing quests in the adventure or buy it the shop in the adventure. There is also a small chance to find the Magic Dust after removing an obstacle in the adventure.
