10. Bongo Bongo
The creature that lives in the darkness.
With the theme of darkness I think the design for this boss is VERY creative and VERY creepy. It has the elements of the unknown in darkness that makes it very fearful.
The area that you battle him is so eerie. The feeling of the battle is different than any other battle in a game because you're battling on his drum. The fact that you're battling on his drum makes it even creepier because it's like you're his little toy.
Bongo Bongo is one of the largest and the strongest bosses in the Zelda series. Though it is very strong, it just has an large amount of health and battling him is actually rather systematic and it gets boring after a while.
What takes off even more points is that it's name is Bongo Bongo. That could be taken as creepy, but it just sounds kind of silly and takes the creepiness away from it. (Of course, this takes off hardly any points...XD)
His background story is also rather petty. He's sealed in a well and then he escapes back to his temple. It's hard to believe it was even sealed in a well. It just seems like it's there. Why is it there? Nobody knows. Something about that I find kind of silly.
