Walt Disney Australia did competent but rather uninspired work for The New Adventures of Winnie the Pooh. It was Darkwing Duck where they really cut loose and began to experiment with Deranged Animation, and Goof Troop is largely considered their signature TV work, establishing the defining look and animating a good chunk of the series.
Also their work on the DTV sequels. Initial projects were about the same animation quality as their TV show episodes. Come the '00s and the transition to digital animation, their style and budget improved dramatically, and the sequels became better and better at emulating the quality of the original films.
The Scrappy: Return of Jafar for the Disney Japan and Disney Australia.
Sequelitis: Most of the overseas studios (especially the Australian unit) get stuck with the sequels.
