Animal Crossing: New Horizons horse mackerel

I caught a horse mackerel! Of course, Mack...er...el.

Supposedly the horse mackerel derives its name from a-false-myth about its strengh as a swimmer. The gist of it is that these fish are so powerful underwater that smaller fish can ride them as steeds! It's absurd, of course. Where would these alleged fish jockeys attach a saddle, much less horseshoes? One does wish that people would construct their legends with a BIT more scientific plausibility!
