The No. 8 engine's page always was previewed by fans using hidden links via the web address bar. But the page itself remained incomplete with missing information and tabs.
Duck's popularity has notably increased since his surprise returns in the Twelfth Series and his absence occuring afterwards during the Animation episodes. This was helped by fan calls and campaigning for a reprieve.
His description reads; Duck is a cheerful, busy engine. He's only a small tank engine, but he'll take no nonsense from larger engines who try to order him about.
Interestingly enough, the profile picture comes from the Best Friends story. Ironically the same image originates from his Thomas & Friends Wikia page, albeit, cropped.
