Don't forget the Saber cat with an axe in a head
Headless Horseman is so epic, but there is no quest with him and he is totaly useless, but I like him, when he across Dragon Bridge I every time follow him just for fun

There is also iced mamooth, with axe in a leg and some arrows on a back, poor little mamooth

and that book... ...I hate it, I can't win that stupid thing, every time I was killed by Thalmor
