Goose Kevin was a member of the goose people species. He is one of the central characters in the episode "The Roast of Twayne the Boneraper".

Kevin is upset when Mark Lilly closes down the Department of Birthdays and gets his birthday party cancelled.

Kevin calls forth an emergency meeting of the General Assembly where his people and other species withdraw from the New York Integration Treaty. It leads to a city wide riot.

Mark goes to Central Park to see Goose Kevin and apologize. Twayne Boneraper brings him a cake to patch things up. Twayne points out that a bomb has been set to destroy New York City. Kevin flies the bomb to the sky and dies heroically in the explosion so that New York City is spared.

Mark later brings his students and some flowers to Goose Kevin's statue in the park in his memory.
