During WonderFest 2018 last weekend, a figma for the Inkling Girl from Splatoon was revealed. She will be able to make different poses like other figma, but the development screenshot shows her in her iconic pose.
It was also revealed that there will be a Deluxe Edition that has parts to make Inkling Girl look like her counterpart in Splatoon 2. [Thanks, @sakai_max on Twitter!]
Splatoon is available on Nintendo Wii U. Splatoon 2 is available for Nintendo Switch.
