LEGO Ninjago began as a toy line and the animated series Ninjago: Masters of Spinjitzu, which premiered in 2011 and followed young ninja trained by Master Wu. Its theme, The Weekend Whip by The Fold, became the sound most fans associate with the show and returned across seasons in different versions. The franchise later expanded with The LEGO Ninjago Movie in 2017. Short clips of the theme now circulate online as a recognisable cue for fan edits, nostalgia posts and videos celebrating the series and its characters.
