The fanfare comes from Dora the Explorer, the Nickelodeon animated series that premiered in 2000. In the show the Fiesta Trio, a small band of animal musicians including a frog, a snail and a grasshopper, appear after Dora completes a task and play a short celebratory fanfare. Clips of their appearances were later shared online as a reaction sound, and the sting spread into memes, edits and children's content as a universal cue for success, encouragement and a job well done.
