That eagle is pretty spankin'.

I have a hunch what this is meant to mean but I can't find a translation that would explain the whole sentence so I'll just translate it as I wish meaning that from this day forward spankin' means: ultimately awesome and superbly cool! And of course the spankin' eagle thanks too. In her own spankin' way.

And thanks! Spankin' thanks!
Spankin' thanking.
Thankin' spankin'?
Thankin' spanks?
Spankin' stanks?
Stankin' fankin'?

This might take a while. At least now I know what I'll do the rest of the day. It's called word wondering.
