Morgie and Moffie have a new brother! His name is Marcos and he is three years old, and he only speaks Spanish. Morgie and Moffie are very excited! They both want to play with him and take him to school for show-and-tell. They are teaching Marcos English and he is teaching them some words in Spanish. It isn’t long before they all agree that Marcos belongs right in the middle of this happy familia.
