Maybe they CAN'T speak...or Nintendo wanted to preserve their classic way of only making sound effects....or they're lazy...Sir Grodus said:I think its the other way around, aside from small blurbs about their personalitys in manuals and guidebooks, the Koopalings were basicly mindless drones, though powerful ones; they only ever speak in the PC version of Mario is Missing! I still don't get why they don't talk in Mario & Luigi: Superstar Saga, all they do there is roar.
