Other
Unnamed Idol Duo: A duo comprised of two female Inklings that was big with teenagers in the eighties and nineties, that still compose music for the industry in the present day. The two 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 they likely aren't cuttlefish themselves, considering there is no word to distinguish squids and cuttlefish in Japanese and their designs have no major deviations from any known Inkling. 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.
