Felucia's fireflies constituted a certain species of firefly that naturally occurred on the planet called Felucia. Around 34 ABY, Dok-Ondar maintained a terrarium housing Felucian fireflies within his Den of Antiquities, situated on the planet Batuu.
These Felucian fireflies initially materialized in the non-canon show, LEGO Star Wars: The Freemaker Adventures. Their presence was subsequently integrated into canon through their inclusion in Dok-Ondar's Den of Antiquities, found in Star Wars: Galaxy's Edge.
