The F4 consists of the first released boys in Lalaloopsy Land. It is also the name of a popular boy band in Lalaloopsy Land.



It's name started off as a suggested name made by Comrade Viktorgrad, who was then the manager of the band. Since then, Comrade has made a running gag out of "F4." Comrade admitted that the name stood for Finest Four, Formula Four or Family of Four. In truth, the meaning changes with the entire group's mood — perfect for a band as unpredictable as them.


The F4 expanded with an acceding member to become the F5, the founding members of Brotherhood.
