Inspired by the YouTube video made by Mayo called "Mario and Luigi have an argument" The "gibberish" Dawn and Toadette are speaking is actually their language, Toadish. Everyone in the Toadverse knows English and their species language. The gibberish I said was me making random noises, if it sounds like a word in another language, know that that was not intentional.
This is not canon. No, they did not say anything inappropriate. Wait 4 seconds after the end screen for an easter egg!
