That's Not a Moo-Cow happened when Jess took Luke to his first country fair. The first farm animal they ran into was a donkey, AND Jess said: "Look Luke a moo-cow". Luke just stared at her and finally shook his head no. Jess explained "Oh, that's not a moo-cow, that's a donkey and it goes 'HEEHAW.'
That's Not a Moo-Cow is designed for children age 2 to 5 years old, helping them to learn their domestic animals as they follow Luke's farm land adventure.
