Worm anus

Worm anus was the preferred way of storing drinks for the Yuuzhan Vong. They would fill up worms with liquids and drink from the anus. It was disgusting. They would not use cups or bowls made from clay or wood because such organic materials are not organic enough. That's just how obsessed the Yuuzhan Vong were with biotechnology. Everything had to be alive. And they liked to drink from worm anus.
