Nintendo has registered two trademarks in Japan that sound a heck of a lot like a certain man-faced fish from the Dreamcast days. Mysterious Partner: Legend of the Fish With A Human Face and Mysterious Pet: Legend of the Fish With A Human Face are the two terms in question, and when we hear the term "fish with a human face," Seaman is the first aqua-dude that springs to mind.

There have been murmurs in the past of a Nintendo-fueled Seaman revitalization on the 3DS, the most recent being a Nikkei report from February of last year. The report posited that a Seaman revival was the first step in a larger Nintendo master plan to revive defunct competitors' products on the 3DS.

Since then, Seaman creator Yoot Saito has designed Aero Porter (as part of Guild01) for Nintendo's handheld. He also tweeted a picture of a Santa-themed Seaman about a year ago, which remains as unexplained now as it was the day he posted it.
