That sounds like an excellent oneshot! “Please Anon, I know it’s uncomfortable for you to go without your wardrobe but would you consider being the model for our figure studies class? You’re literally alien!” It’d then be advertised to hopefully increase traffic to the class, ‘Next Sunday is your once in a lifetime chance to see the hidden anatomy of an alien at this week’s drawing class!’ Hilarity with Lyra ensues. But it’s gotta be clever. The trope has been played out and needs to be funny
“Seriously? What kind of monster IS this?”
