Nightkelp flail

Nightkelp flails were a type of musical instrument made from a length of nightkelp containing bioluminescent seeds that made sounds when the kelp was twirled around. The flails were made by members of the Lanai species on their homeworld of Ahch-To, and the Lanais who inhabited the Caretaker village of the Temple Island there owned one.
