Seriously... the rabbit IS Kaguya. The Tailed Beasts aren't 100% of the Ten-Tails chakra. Had Hagoromo separated all of her chakra, Kaguya would have died. The rabbit is what remains in the body when you take away the portion of her chakra that the Tailed Beasts have. You could say it's the "tenth" tail so to speak.
