Master Sheep was one of the twenty-nine representatives at the Jade Palace's formal Winter Feast dinner for one of the unnamed kung fu schools in China, of which he is the master over. When Po stood up to give his speech, Master Sheep was regarded to being "fluffy and incredible". Sheep, like the other masters at the table, was inspired by Po's determination to be a good son to his dad over being a good host, and joined the other persuaded masters as they made their way over to the festivities at Mr. Ping's noodle shop. The guests, already there, marvel at all the masters' arrival.
There is nothing else known about Sheep aside from these events.
Like some of the other twenty-eight masters at the Jade Palace's formal Winter Feast dinner, Master Sheep wears a long silver-laced robe underneath his dark wool.
