While Team Avatar was staying in Ba Sing Se, three pygmy pumas attacked Momo when the winged lemur ventured out into the city searching for Appa. Before they could catch him, however, they were all captured and sold to a butcher. When Momo escaped his cage and wanted to escape, the caged pumas whimpered for help. Momo freed them, and the animals all escaped together. Now formed a friendship, they retreated to a rooftop, enjoying the view of the city. Noticing the piece of Appa's fur Momo had tied around his wrist, one of the pygmy pumas tore it off and ran away with it, its two companions and Momo in tow. They led the flying lemur to a footprint Appa left behind when he stood in the mud. As a forlorn Momo curled up in the middle, the pumas sat beside the print and watched.
