If you are like me and are so annoyed about getting stuck in bogs in the Great Marsh and the Safari Zone all you have to do is this:

If you are trying to go left or right squirm about pressing up, down, up, down and then left or right (whatever direction you wish to go in)

If you are trying to go up or down squirm about pressing left, right, left, right and then up or down (whatever direction you wish to go in)

I hope you find this useful in bogs so you don`t get over-tempered and smash your DS.

Note: Sometimes once you are freed you get stuck in the very next spot so this trick is extra useful, because you don`t step the wrong way, and thus you save steps.
