Every Day They're Out There Knitting DuckTales, Woo-oo! is a short non-canonical animated spot featuring the DuckTales 2017 versions of Huey, Dewey and Louie Duck, Donald Duck and Webby Vanderquack.
Motifs representing the Ducks on a set of Christmassy sweaters come to life!
Behind the scenes
This spot, promoting DuckTales 2017, was presumably aired on Disney XD during the 2018 Christmas season. It was posted on 2018 on Twitter, and, soon after, uploaded on YouTube.
