Ahh, yet another mind-boggling glitch has been found in yet another famous game! Go to Crystal Caves with Donkey Kong, go to the #2 warp (if you haven't gone through the waterfall, go through it and climb up the rock "steps" to get to where I mean) and look around. You should see a lone, elevated cabin that has a musical pad in front of it. Play on it, go inside, and you will see two switches on the ground in front of you. Pound the one on the left, and you will see the cabin tilt. Next, pound the yellow pads. This will start a timer. Then, pound either the blue or red pad. Finally, pound the switch, and while the cabin's tilting, push the Controller Stick over to the right as far as possible. If you do it right, you will see the cabin continue turning as Donkey runs onto the cabin floor and fall through it to a lit up space below! This reminds me a little of an infamous glitch once found in Super Mario 64 where you had a very strange perspective of the castle... I'm sure you're familliar with it; if not, sorry, I'm not saying any more.
