Schrödinger's beetles
Shikamaru uses Shino's beetles as a shadow to incapacitate him. But wait! Just because Shino can't move, doesn't mean the beetles can't. But wait! Shino's beetles have their own shadows too, so it'd still work, right? But wait! The beetles can eat chakra, so the shadow possession shouldn't work through them...right? But wait! They already can't move, so they won't be able to eat through the shadows, right? But wait! (x5) The bugs' shadows might be too weak to shadow possess. Who comes out of this situation??
