Mcmoo is the main hero of the Cows In Action books. He is an Emsy Square, but is extremely intelligent even by the standards of that breed, able to build and use complex machinery.
He Likes Cups of tea and id close to his friends Bo and Pat. Like Bo and Pat he is very clever but a bit off on timing. In World War Moo it is shown that Odette LaBarmer (An ancestor of Bessie Barmer)) has a little crush on McMoo and his bravery. Not mentioning his love of tea. His last appearance is on The Dinosaur Moo-Tants when he and the astrosaurs defeated Toro, the leader of the FBI and the Raptor Royal.
