Juanito Jones
In several episodes it is possible to see cameos and references to the series Les Tres Bessones, due to the fact that both series are produced by Cromosoma and Televisió de Catalunya. In two episodes it is possible to see the characters watching on television the cartoon of the Witch Onilda, but under the name of La Bruixa Avorrida (catalan for "the Bored Witch", which is also the name that the series received in Portugal). In the episode where Vanessa steals Juanito's Shadow he mentions that the only magazine Vanessa read was the Triplets. Also, in the episode where Pedro's sister returns home when she tries to pull a rabbit out of her hat, what ends up coming out is the Witch Onilda's owl.
