Right now, the tail is coiled and piled around on top of the Rat Thing's body like a rope that has fallen out of a tree. Parts of it are trying to move, other parts of it look dead and inert. The legs are moving one by one, spasmodically, not acting in concert. The whole thing just looks terribly wrong, like footage of an airplane that has had its tail blown off, trying to maneuver for a landing. Even someone who is not an engineer can see that it has gone all perverse and twisted.
