Disenchantment viewers definitely noticed quite a few background characters in this universe who vaguely resemble popular Simpsons and Futurama characters, with this elf being one of the most distinct ones.
Fans will spot her a few times throughout scenes set in Elfwood, even though the actual character adds little substance to the show overall.
It’s a shame really, as I imagine she’d be a decent saxophone player if given the spotlight!
Sure, Lisa Simpson doesn’t have a green tuft of hair coming out the back of her head, but this elf’s distinct yellow color, spiky hair, and orange-ish dress seem like obvious nods to the young Springfield genius.
