Uhmmm… dolphins have reputation for “riding” other dolphins and even other species in a not-so-piggybacking kind of way…

Just sayin’.

This could be an album cover for some feel good music.

Or maybe you can add some dark filters to it and use it for heavy metal.

Holy crap that is adorable. Fuckin’ just piggyback riding and enjoying the shit out of it. Arrgh, my cute aggression is really hard to fight on this one…
