The first thing I thought of was a baby? I have no reasoning for this ¯\_(ツ)_/¯ but after viewing the comments the ones I fully agree with crayons and chlorine
Given that he is put off by strong odors on Earth, I would assume he has a very neutral and nearly absent scent of his own. The backpack and mechanisms in and around him all the time may leave a metallic scent
I think he’d smell like either Chlorine or artificialy flavored grape juice. If there exists a combination of the two then that but I don’t want to imagine what that might smell like.
It’s funny, I always switch between him smelling like nothing, or him smelling like my dogs old, dirty potty pad that smells like expired milk, onions, toxic waste, and just smells really sour in general. (Sorry for whoever reads this 😭)
I imagine he’d smell like one of those stretchy aliens you’d get in the egg shaped containers with slime in it, kinda artificial smelling and a little unnerving, and once you touch him you can’t get the smell off your hands no matter what you try
Honestly I agree with the Play-Doh thing. And in the most none sus way possible, that makes me want to take a bite. Like...anyone else try to eat Play-Doh when they were younger? In fact we made edible Play-Doh once and I devoured that shit.
