In 1985 a new character, the "Bored Witch" (La Bruixa Avorrida, in Catalan) was added to the plots to form a collection of classical stories, "The Triplets and (...)".
In 1994, television producer Cromosoma [ca; es] and the Catalan TV corporation Televisió de Catalunya adapted the stories to make an animated series based on the books.
It became very successful and profitable and led to the production of a second series with the Bored Witch as the main character, together with France 3, Canal J and Storimages [fr].
Sometimes they play some prank or manage to annoy the Bored Witch, and, to punish them, she sends them into a classic tale, legend, or children's or adult's (such as Frankenstein or The Phantom of the Opera) literary work.
The main structure of the classic remains, but some twists (often hilarious anachronisms such as showing The forty thieves getting distracted from robbing a house by a camel race on TV or Dr. Frankenstein as a veterinarian) are introduced to favor each plot and define the sisters' personalities.
