UK cortana won't talk me what a fox says

[original.woodster]

Cortana is brilliant, been using the feature alot. I've managed to get her to tell me jokes, riddles, stories and do impressions, however she won't tell me what a fox says. What is needed to be said to trigger this?

Also with the US getting some new animations, week we be seeing these? I'm guessing they're tied in to the impersonations due to the image.
