don't forget that the tail of hell looks like picrel, and Spamton's heart (his soul?) on a chain as well as his phone arms attack have a similar look. King also has the spade-with-mouth in his belly, although it lacks the "bead-necklace" attachment look, so maybe that is specific to cyber Darkners, or Spamton through FRIEND interference?
Given that King, Queen, and Tenna all have little charms with smiling mouths in their attacks (spade, heart, and star/spark respectively), those may represent the base forms of their souls. And Spamton has the heart with his cute face on it.
