Can't take two steps. Easy to kill. Serve only to slow me down. Nothing but a nuisance.

But they don't fly.

Nor do they skree.

Not nearly as bad.

LoL, no.
Nothing in Skyrim can even compare to Cliffracers.

Wolves attack and get defeated in a sec.
A cliffracer will chase you, but decide not to attack you, but follow you no matter where you go or how fast, and then, when you are in biggest trouble, it will attack you, but he will have a ton of buddies now with him too!
