Theres two I remember. One from an old Mario game on the Game Boy, the name of which I cant remember. Used to play it a before school club. There were these 3 fat pigs which you had to beat, the first one rolled, the second jumped and the third did a higher jump. It took me ages to beat the third one although the first two werent a problem.
The next was on Metroid Prime Hunters for the DS. Remember you had to find this crystal-like things to unlock something, and the bosses that guarded them were a nightmare. On the third one I got so close to beating it but I made a mistke and died. Wasnt able to play it ever again, and traded it in years ago.
