Everything about Snuffleupagus is sad. He sounds sad. He looks sad. He's slow in body and mind, and he's eternally four years old, which is far more creepy than adorable. And since he's more or less a woolly mammoth, he's a giant, slow-talking reminder of species extinction. Fun fact: The Sesame Street producers made an episode where Snuffleupagus' parents get a divorce, and Snuffy and his sister Alice get really upset. Shockingly, this episode make children so sad they never aired it.
