Other characters include Ludwig Von Drake, Knuckles the Iguana, Gwumpki the cook, Kent Powers, and Moltoc.
Quack Pack appeared in 39 episodes on syndication on network TV from 1996 to 1998, but now it can be found on Toon Disney.
There is some question about whether Quack Pack is supposed to feature the same versions of the characters as Duck Tales. One episode mentions that Donald used to be in the Navy (as he was in Duck Tales), but there are no unambiguous references, and Scrooge McDuck is never mentioned in a single episode.
