Widely regarded as the stupidest Disney animated character ever, Hei Hei the chicken from Moana was not only comic relief, but a subtle hero. Sure he's as dumb as the rocks he tends to eat, but as Moana herself pointed out his "strengths lie beneath the surface...deep beneath" and he was there at a critical moment to save the day. Builder LEGO 7 captures his vacant essence perfectly.
