Donkey Kong Country is one of my favourite old school SNES games. For this game, I went for a 101% score. Every level and boss beaten and every bonus room explored. There are two 3-up balloons hidden at the end of Jungle Hijinxs that not a lot of people know about. To get them, run up the end of the level cave with Rambi, jump, and dismount him at the peak of your jump. You'll hit a bouncy tire off screen and enter a barrel cannon, which will launch you into the two balloons. You need be quick though, or they'll float away. And yes, I used the shortcut to skip Mine Cart Carnage. Since there are no bonus rooms in that level, using the shortcut won't hurt your score. Which is nice, because that level is pretty hard.
