Just so you know, Poly only pulls himself in like he did then if he feels he needs to protect himself, or when uncomfortable/scared (this shows in the Terrorwing reference, where Terrorwing's large and intimidating appearance made Poly mortified, but he refused to show it, but it barely worked)
gosh he look like Lego with the way he just pieces together also those sunglasses being pulled out is a sign that he feels threatened, and in-case you didn't already figure it out, those are basically like car keys, except it doesn't activate a car, it activates something much worse. How will Fake CYU respond?
