Hi, china. That's a little odd. Normally, you wouldn't be able to get the head of the navigator unless you had already gone down into the monkey head cave. To get into the cave, you need the giant Q-tip from Herman, which you wouldn't have gotten unless you already gave him the banana picker. So you might have already given it to him and forgotten about it...or you found some sort of crazy-ass loophole that the rest of us can't quite figure out...lol.
The game's hint system can be a little off from time to time, and sometimes it gives you hints that are obsolete. Since you already have the head of the navigator, have you tried going down into the monkey head cave(which you hopefully can do) and using the navigator's head?
