The "City Beyond the Last Horizon," the mysterious civilization known as Panda-La is perhaps the grandest legend known to explorers. An ancient city somewhere in the mountains of the far east, magnificent Panda-La was supposedly filled with wonders beyond imagining — giant pagodas that reached up to the sky, gold and silver treasures rivaling those of the world's richest empires, and much more.
Though the story of Panda-La had existed for untold centuries, no one could prove whether or not the city really existed. Many explorers tried desperately to locate the legendary civilization, but could never reach it. As they explained, Panda-La would be right in front of them, a glimpse just over the next mist-shrouded hill — but after a mad rush to reach the spot, the explorers would find nothing. Countless searches for the elusive city all ended the same. If it ever did exist, Panda-La truly was "beyond the last horizon," always too far away to grasp.
The one person with the best chance of finding Panda-La was Baloo, who had a similar encounter with the lost city several years ago. Determined to prove himself as worthy of public praise as celebrated explorer Monty Mangrove, Baloo left his companions behind in a quest to find the City Beyond the Last Horizon. Days passed before a violent sandstorm stranded the Sea Duck in a desolate mountainous region; but here, Baloo finally discovered what he'd traveled the globe to find — the city of Panda-La.
Nestled in a fertile valley on a huge rock perched high atop a mountain peak, Panda-La indeed had all the splendor of the legends. Giant pagodas filled the mountaintop countryside, and the Pandas themselves were friendly and prosperous, just as the legends claimed. But despite their generosity, the Pandas acted somehow cautious and reserved, as if they were harboring some secret. When Baloo returned to Cape Suzette, that dark secret was revealed. Transformed into a monstrous airborne armada, the entire city of Panda-La had followed Baloo home, with the sole intention of conquering Cape Suzette.
The Pandas of Panda-La proved themselves an exceptionally duplicitous people, pleasant on the outside but treacherous and warlike underneath. In their floating cities, the Pandas had been able to conquer ancient cities (at least those foolish enough to send ambassadors to them) by means of powerful weapons. Not all Pandas were ruthless as those of Panda-La — these lived to conquer, and where they conquered, they lived. This peculiar trend also explained the aforementioned elusiveness of the city. With inflatable balloons stored in each building, the entire city could move to a different location in a matter of hours.
Armed with cannons and special heat-seeking missiles designed to chase aircraft, the Pandas laid waste to Cape Suzette's cliff guns and defense squadron. Most of Cape Suzette evacuated before Baloo, vowing to make up for his terrible mistake, flew off on a virtual suicide mission to destroy the flying city. Aided by his friends, Baloo heroically managed to wipe out the entire Panda-La fleet — sending the City Beyond the Last Horizon to its final resting place, beneath the waves of Cape Suzette's harbor.
