The studio of the show as been reduced in size, but the show must go on, and Mayra and Kim greet the returning Silvia from the third season who has returned after studying hard music and dancing and show what she has learned, and also four new secretaries, Victoria, Isabel, Jenny and Beverly. Also, Mayra greets two new puppets who will substitute Chollo and Antichollo, they are El Boom and El Crack. They are two home-less who tried their last coin in a casino. Boom won the Jackpot and Crack lost his last coin. It's not that they're good or bad, it's just that Boom represents the best luck and Crack represents the worst luck, so Boom will be the positive puppet and Crack the negative puppet. The Miserly Ladies claim Mayra that they, like Silvia, have also prepared hard themselves to be harder than ever with the contestants.

After Nina is introduced, they start watching her, wondering what's so special about her.
