How do you get the third coin in New Super Mario Brothers in world 2-5?

Answer 1

Ok. When you get near to the end before you go through the pipe you see a person(dunno what they are called soz) throwing daggers. Try and defeat him. After that you can see the quick sand (mud.) Under the yellow pipe you can see a grey box. Go underneath the mud and swim to the box. You can see that if you go through there you can see alot of grey rectangles. Follow them down. (Try not to fall because there is a hole.) Jump from where the rectangles are to the other island. Keep on going and then you can see some walking boxes. Jump ontop of that and when it jumps you will be able to see the coin. :) if you don't follow then reply and I'll try to make it more clearer.

Good Luck!
