When a hummingbird named Doodle discovers that magical Keystones have vanished from Haven Tor's mystical gates, she awakens her serpentine companion Noodle to help track down whoever orchestrated the theft. The two unlikely partners embark on an ascent through a series of fantastical biomes—lush jungles, aquatic zones, volcanic landscapes, and wind-swept regions—each guarded by its own perils and puzzles. As they make their way upward toward Haven Tor's peak, cryptic clues emerge in the form of mysterious winged silhouettes and dark feathers scattered across their path, gradually pointing toward a larger mystery waiting above. With the gates sealed and their world thrown into disarray, Doodle and Noodle must rely on each other's unique abilities to navigate hostile terrain and piece together the identity of the thief responsible for the chaos.
