Sure! But it takes a lot of practice. You have to think about everything when you're making it. I've been trying to make a paopu fruit, but I think I keep getting the smell wrong.

[he figured the Keyblade had ended up being easier because... well, because he didn't really need to know specifically what it was made of, just how it worked. it was a feeling, maybe more like an ability, or at least way more than it was just an item.]

It gets easier the more you make stuff, though. Then you don't have to think about it as much.
