Nonetheless, she wants to find out if there really are ghosts in the mansion, inhabited now by a strange former servant named Chon. Sofia secretly enters the mansion to recover a picture of her mother, who died when she was a baby.

There, she meets Alfonso, Chon's grandnephew. To their amazement, the children discover Don Darvelio is not dead, and he is the one who has been "haunting" the mansion for the last few years.

The old man finds the happiness he had been yearning for in Sofia and Alfonso and he names them "Alegrijes" (or Happies) who enjoy life, never lose hope, share good and bad times, and keep the wonderful gift of amazement.

Sofia, Alfonso and Don Darvelio have incredible adventures that they share with other neighborhood children: Allison, Ricardo, Ernestina, Pablo and even Esteban, Sofia's disagreeable brother.

Don Darvelio decides to transform his mansion into a place where all the children and their families can live together. However, he becomes seriously ill with the arrival of Helga, his wicked ex-wife, who wants to take over the mansion and destroy the dreams and love the old man has created.

In order to overcome Helga and her mean allies, the "Rebujos" (or Grumpies), the children must employ their best values: friendship, truthfulness, fair competition, love, and happiness.
