Shy-Ho-Shy

Shy-Ho-Shy is the Squid Sisters' original music producer. Although she is never seen in the SS undefined, she is mentioned several times in the booklets included with official soundtracks.

Description
Shy-Ho-Shy is first mentioned in the booklet for Splatune as one of the committee members that heard Callie and Marie perform at the Inkopolis Youth Folk-Singing Contest, becoming their producer soon after. Shy-Ho-Shy created a demo version of City of Color, the Squid Sisters' debut single, as a reference for them during the making of the song; this demo is included in Splatoon Live in Makuhari and features Shy-Ho-Shy's own vocals. Marina mentions in her interview in Splatune 2 that she is in contact with Shy-Ho-Shy. In the interview in Splatune 3, Marie mentions that Shy-Ho-Shy wrote the melody for the song Wave Goodbye after Callie wrote the lyrics; however, Big Man then points out that the song Tomorrow's Nostalgia Today instead features a new producer, You★Me.

Etymology
Shy-Ho-Shy's name is a reference to her real-life counterpart Shiho Fujii, the composer originally in charge of writing music for the Squid Sisters.
