As practice with drawing Noryoo, here's a picture of two searching through a trash dump.
On their homeworld Evertox, many Noryoo live in or near one of the leftover trash dumps. They would sometimes search through the garbage for something to eat or for useful items. Noryoo like to find things that can help make their lives a little more convenient. They also aren't picky eaters, as they can safely digest rotten food and a wide variety of materials.
