" Radda Radda Radda Radda."
" What do you mean I wouldn't understand?"
" Radda Radda Radda!"
" What do you mean stop repeating everything you say?"
- Schnitzel and Chowder
Radda is the main word in Shnitzel's vocabulary. While it is hard for us to figure out what he is saying, some of the characters (mostly the main characters) have no trouble at all deciphering his speech. Other characters who talk in a way like Shnitzel are Foie Gras, Backwards, Flitzel, presumably Shwitzel, and the Queen of the apprentice games.
