Frazzle has talked in regular English ONCE. in a Furry Arms Hotel Episode we think that an anything muppet has him as a pet but its the other way around and Frazzle says "Oh well. Come on, bla bla" in a very civilized matter. And i think monster laguage is a real language because elmo and telly wanted to learn to be a 2 head monster and when they tried repeating what the 2 headed monstewr said, they were saying mindless giberish at first and the 2 headed monster mocked them. so basically its a real language but it could sound like gibberish. and if you dont get it right, you could end up looking foolish abnd having the 2 headed monster making fun of you. now, who wants that??
