In each scene that Paucha is not wearing his poncho, he is shown to have a white shirt and a brown "skirt". In scenes where he is wearing his poncho, he appears to be wearing a brown robe. For the period of time this was set in, it would be a robe, i.e., all one piece. Why this wasn't colored in, is very annoying, as the mistake is quite obvious. The first time this is seen is when Paucha and Kuzco have gone down the falls, and Paucha's poncho is off to dry. Then when Kuzco is wearing the poncho to get into the restaurant.
