Cuttlefish Idols: A duo comprised of two female cuttlefish that was big with teenagers in the eighties and nineties, that still compose music for the industry in the present day. The Cuttlefish Idols are unique in that they do not have any listenable tracks and were only described in HaikaraWalker. However their music artwork can be found floating in the background Stick 'n' Move Station with the artists removed, although one of their forearms remains. When translated, the text on the top-right corner reads" COIKARS" in Halfmoon script, which may have been the name of the duo. This is a play on コウイカ, (kouika, golden cuttlefish) though it is currently unknown whether they are considered inklings or not, considering there is no word to distinguish squids and cuttlefish in Japanese. The text in the bottom-right corner, when translated from Bold script, reads "pop pop pop", "hakkisyon!", and "Bye bye", which may have been some of their songs.
