This Disney Afternoon commercial is quite interesting. Not only because this is animation footage made specifically for it (not taking anything from the episodes).

This also may be the first and only time I see these characters interacting together!

Some of the characters that appear : Darkwing Duck (Drake Mallard), Gosalyn,Honker,  Kit Cloudkicker, Huey, Dewey, Louie, Scrooge, Baloo, Launchpad.

If only they could have made an episode like this!
