I Want to be Alone!

Tish wants to be alone for the weekend, but despite her friends asking, she ignores them. While her friends ask around to see what's up with her, they decide to speak with her mother, in which she says she is with "Cows and Duck". Can Lor, Carver and Tino figure out where Tish is and what "Cows and Duck" means before the weekend is waisted?
