Unlike the regular Jönssonligan, the kid version was an original Swedish idea, with Denmark and Norway later following suit, with Olsen-banden Junior and Olsenbanden Jr. respectively.

Lilla Jönssonligan och cornflakeskuppen takes place in the 1950s and works as an origin story for the gang.

Lilla Jönssonligan och stjärnkuppen does not take place in the same canon as the first three films or the original series as it is set in modern day.

The gang consists of the criminal genius Charles Ingvar "Sickan" Jönsson, hence the name Jönssonligan, and his two companions Harry (aka Dynamit-Harry) and Ragnar Vanheden.

The gang's arch-enemy is Morgan "Junior" Wall-Enberg and his henchman, Biffen.
