So i realized that Pico has some black things on his ears.
Are they headphones?

I think that is just part of his design, as such, he is a weird alien thingy, I think those are just weird alien thingy things. (No offense scratch.) But if you want them to be headphones, then they can be!

I think they’re just part of his head?
