Alegrijes y Rebujos (English title: Don Darvelio's Secret) is a Mexican children's telenovela produced by Rosy Ocampo for Televisa.

Alegrijes y Rebujos follows the story of the ghost of an eccentric millionaire, Don Darvelio, who is said to haunt the mansion.

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.
