Alright this one is just a funny headcannon to escape having to update my other book-
So I headcannon that any crowns, hats, or whatever is on your head, floats everywhere you go.
Like people who have head pieces or crowns or hats use a trident that has like that one enchantment that let's you glide in rain, their hats or things will fall off normally so that's why I say they all just float!
Just imagine, philza is using his trident to get somewhere and as soon as he is off the ground his hat just follows him without being on his head, or if techno is swimming somewhere and he's underwater, his crown swims like close to him.
I just feel like this could be a possibility for everyone who wears something on their head!
