AFAIK, the really cruddy ink and paint stuff for Calvert was done in Thailand, not Korea (or even Taiwan)...

That's correct! I personally don't know where in the word we associated the Calvert production as having been sent to Korea in the first place, as the credits do mention the Thailand studio otherwise, but perhaps we're just rather too used to where most US cartoons get sent to these days and often don't realize there's other Asian studios this stuff could be sent to (China, Taiwan, The Philippines, etc.). Wang Film has been involved in animating many US cartoons for many decades, often also under the name "Cuckoos Nest Studios".

Oh look, here's their webpage!
