Found a typo/grammar issue. When you talk to the guy at Corneo's mansion before you go in and he chuckles to himself about a friend, he says "The don'll be happy." I'm pretty sure don should be capitalized, although I could be wrong.
Okay, I'm assuming it's not an issue at all as he was mentioned by his title in another place and it was also lowercase. Given its a title, it might be better off to capitalize it? Then again, if it was translated you probably wouldn't capitalize it so I get it if you don't, too!
