"A La Nanita Nana" is a traditional lullaby in honor of the Baby Jesus that has become a very popular Christmas carol within the Spanish-speaking world.

As Sam continues to increase his Spanish vocabulary, Lola and Ana seem increasingly intrigued by their foreign friend.

Pablo and the girls compete to take Sam shopping in an attempt to get him to reconsider his eccentric style.

As Pablo tries to teach a confused Sam the names of the articles of clothing in Spanish, the girls fight over which parts of his body each will be in charge of dressing.

Professor Graciela Simancas helps us take our first steps with Spanish by teaching us the letters of the alphabet, the vowels, and some very common words.

Sam calls his mother to tell her how excited he is about the prospect of his new friends dressing him in hip Spanish style. Later, while brushing up on his shopping terminology, he receives an unexpected call.

While looking for a gift for their Grandma, Guillermina and Candelario encounter a starfish and contemplate its origins.

While in Colombia, the second person plural pronoun, "ustedes," is typically used to address more than one person as "you," both formally and informally, in Spain, "vosotros" is much more commonly used on an informal basis. Carlos and Xavi provide us with several examples of how the same idea would be expressed using either "ustedes" or "vosotros."
