In Ty the Tasmanian Tiger
These volcanic beauties are the key to powering Julius' talisman machine. This machine locates and teleports the missing talismans back to Rainbow Cliffs. But you'll need at least 17 thunder eggs to get it to work. You can either find or earn thunder eggs by completing tasks, solving puzzles, or by successfully completing time attacks.
These magical geodes are used to power Julius' talisman machine. Thunder eggs come in three varieties. The first type of thunder eggs you come across a fire thunder eggs, which are colored red. The second are ice thunder eggs, which are colored blue. And the final are electric thunder eggs, which are green.
