WoW Mists of Pandaria Beta: Portal Panda
Another change to Orgrimmar is the addition of Ka Pao, the Portal Panda. He most certainly is a Beta-only feature, as he instantly transports you to your choice of one of three locations within the Jade Forest. I assume the initial transport to the Jade Forest would be through some action similar to the zepplin ride to the Twilight Highlands in the Cataclysm expansion.
