Since Po is the Dragon Warrior and Tigress is obviously a female tiger, both symbolize Yin and Yang which is a fundamental part of Chinese culture...the people behind KFP have no choice, but to put Tigress and Po together.
Sooo, what's the official ship name? I mean, I shipped them before the first movie even came out, and I don't even know what to call it. Tipo? Tigro? Pogress? Pigress?
