I can tell because of the Elmo puppet that dates from around Season 11-13. He has smaller eye pupils and a bigger, longer, crooked nose. And Elmo's original character concept, which the writers came up with, is that he was a red monster who tries to learn English or Spanish but would obsess on repeating a word over and over again (i.e. "Casa!"). But the character appears to talk like an out-of-breath panting caveman, and as Muehl states, "Elmo must be a junior version of Animal!"
