I mean… what else was I supposed to think when Goku in Dragonball Z: Kakarot literally took what looks like a butt plug tail, inserted it into what I can only assume was his asshole, and then, knees together, waved his butt around demonstrating how Gohan could fish with his tail.  WHAT IN THE WORLD WAS I SUPPOSED TO THINK WAS HAPPENING?

Where, exactly, else could the tail be inserted?
