Kamabo Corporation
From Inkipedia, the Splatoon wiki
Kamabo is a company in the Splatoon 2 Octo Expansion. It is the company that operates the Deepsea Metro and C.Q. Cumber's employer. The company's logo is made of two wave shapes that form a sea cucumber and appears throughout the expansion in loading screens, challenge selection, and on various item (such as the CQ Card and C.Q. Cumber's hat). The logo is also seen on the Rainmaker and the Tower in the tests instead of the regular Ranked's anchor logo.
Etymology
Kamabo sounds like a part of the word Cucumber.
