So, interesting that Darkwing Duck is 'just a TV show,' but S.H.U.S.H and F.O.W.L are both real things, apparently.
This does seem to lend some strength to
digiman619's theory.
Also, nice Ludwig Von Drake cameo. Interesting they did not use J. Gander Hooter as the director of S.H.U.S.H instead.
Oh, and I loved the Gummi Bear references. The berries, the juice, the sound effect that the juice makes when you drink it and when it wears off, the reference to the theme song, namedropping Dunwyn Castle...heck, they even got the recipe for the juice right (but left out the proper stirring technique)!
