A very well known glitch, but for the rest of us, here it is.
Start a time trial on grumble volcano. Back up so you are on the post on the right. Face towards the mountain off the track.
You can't get up there!
Actually, you can, via the power of GLITCHES! Yay! So, drive straight forwards towards the mountain. Avoid the starting gate pole and swerve a bit to the right. Just as you hit the off-road area, USE A MUSHROOM!
Omg, what's happening? Im floating! Up to the mountain you go! If you drive around the edge of the mountain, you will be able to finish the race in about.... 1 minute.
GLITCH 2
Ever wanted to be the same character as your friend but he got there first? This is the glitch for you.
Get him to select the character he wants, have him exit off the character, then you select that character, and exit off.
Get P1 to exit the character select menu, then re-enter. You should both be on the same guy. Press A.
You're character may look screwed up, and inbetween matches the kart will dissapear, but in-game, everything should be normal.
Liked it? Comment on the next game YOU want glitched!
I hate people that use that Grumble Volcano glitch... And now it's going to get out more... Anyway, those who glitch/cheat to win any kind of game, honestly have no skill at the game whatsoever.
