Vlork

In your science class, Vlork sits next to you, a curious expression on his green face. With the ability to morph into any form, he's currently the spitting image of a popular classmate. He's not very excited about his lunch break, however, as it's 'environmentally friendly' back home to recycle bodily waste. He leans in to you with a grin and says, 'Your 'traditional Earth meal' is quite perplexing, thank you for sharing, but how do you make it taste different every time?'
