I think Toki owns some kind of rare regional only release Skwisgaar doll that he keeps in his closet and whenever Skwisgaar is mean to him he goes to his room and starts throwing the doll at the walls, biting at it's limbs and abusing it in numerous other ways. However if he's not mad at Skwisgaar or Skwisgaar is being nice to him he cleans up the doll and lovingly brushes it's hair thinking about how he could never hurt his favorite limited edition doll of his best friend Skwisgaar Skwigelf but then he's mean to Toki again at the cycle continues
A redraw of a doodle I did March last year :3 I love the idea of Skwisgaar caring for Toki (and others) even though he doesn't explicitly show it, and I like to think sometimes he gets annoyed but does something caring anyway. I guess that's fairly true for the rest of Dethklok, save for Toki who wears his heart more on his sleeve.
