How can I breed Water or Electric Animals?
The base creature for Water Animals is the Frostfang - a wild creature that roams free in the uncharted areas of the island. Once you reach Level 10, you can expand your island into the Frostfang's land; then, you can breed all new Water type animals!
To expand your island, first look for and tap an Expand sign near the edges of your island. Expansions can be purchased with Coins and/or Realm Runes earned from Mining. After you purchase the expansion, it will take time for the area to be habitable for your animals!
The Lightning Leopard is the base animal for the Electric Animals. Like the Frostfang, you must expand into the Lightning Leopard's home to bring it to your island.
