Hi! I tried copying and pasting your code into the challenge (because it looked right to me), and I found that if you put a space between cuddlyName: and String, it accepts it.

Like instead of

var cuddlyName:String { get }

put:

var cuddlyName: String { get }

If that doesn't work for you, maybe try reloading the page and paste it in again? Hope that works for you!
