The Everett AquaSox compete in the Northwest League and currently are the Class A Short Season affiliate of the Major League Baseball team Seattle Mariners. The franchise was founded in 1984.
The fact that the logo of the Everett AquaSox depicts a frog seems completely natural – there’s so much rain and moisture in Everett that this creature fits perfectly.
The overall look has remained the same, only a couple of minor updates have been introduced. According to the official press release published in 1995, it’s not just any frog, but a combination of a Pacific tree frog, a red-eyed tree frog from Central America, and, strangely enough, Brooks Robinson.
