Mamet is the lovably delusional sheep of Lubberland Farms. He arms himself with a lethal combination of ignorance and arrogance, and believes in speaking before you think. His laughable schemes for becoming rich and famous are only matched by his unlucky attempts at love.
Cobb, the older of the two dog brothers, is wise and true. Honesty and hard work are his compass. He desperately tries to keep the household together, while shielding the world from Mamet’s antics. A losing battle, at best.
Rupert, the younger of the two dog brothers, is optimistic and loyal. His simple worldview clashes with his housemates’, and he often becomes an unwitting accomplice to both Mamet’s and Tucker’s schemes.
Tucker, the human boy being raised by Cobb and Rupert, is a social misfit who seeks out his own path. Genuinely smart, but easily distracted, he has yet to meet a rule that couldn’t be demolished.
Marshall is Mamet’s friend and the only black sheep on the farm. Mamet loves having a hip friend.
The Gerbils are Mamet’s arch-nemesis, and the two sides engage in an endless struggle of one-upsmanship. It’s like Spy vs. Spy, but with more wood shavings.
The Cows are the no-nonsense locals of Lubberland Farms. They intimidate Mamet, and will often put an end to one of his plans with a well-placed hoof.
