DuckTales

According to Matt Youngberg, Huey, Dewey, and Louie have more developed characteristics in this show, whereas in previous shows they were indistinguishable from each other. "Everyone always says Huey, Dewey, and Louie in that exact order, so we decided to make that the birth order, and by defining that we were able to assign traits that fit. Huey's the oldest, a little more responsible, a little bit brainy. Dewey wants to stand out, and wants to break out of being labeled as just one of a set of three. And Louie is happy being the youngest child - he can slip under the radar. Huey has Scrooge's brains, Dewey has Scrooge's guts, and Louie has Scrooge's love of treasure."
