Huey, Dewey & Louie make their first appearance as a trio on BPA (Dewey previously made a solo appearance). These guys were part of a Kinder egg surprise set called "Mickey Mouse & Friends" from 2013. They are all the same mold but painted differently. Their colors (which are usually the only way to differentiate them) changed quite a bit in the early cartoons but stabilized for Duck Tales. Speaking of Duck Tales, it looks like a reboot is on the way.
