Sparky handles his flame with caution these days. He can blow four perfect smoke rings by now! But Sparky feels...different. He thinks he doesn't belong in Horseshoe Forest! The tree friends, Sparky, Daisy and Benny, go looking for Sparky's dad in the mountains. But little horses aren't suposed to go strolling through the woods by themseles. Before they know it, the three of them are in big trouble! They are all alone in the mountains where leopards and dragons hide. Then it gets dark ... A massive shadow hides the sun ... "Call me Firestorm," the dragon smiles.
