Hiya, you can land on the left side of the Question Mark at the bottom of the dropper, the right side will lead to your death while the left side leads to water!
Hope this helped!
You need to go to the far right side of left of the question mark, as the right is going to lead to a room with no water and death. If you keep hitting the 2 by 2 just try to go on the bottom of the first 2 by 2 and then go on the top of the second 2 by 2 using (the key you run in MC). Exemple mine is shift so use that key you run with in mc and you need to hold D right after the fist 2 by 2 hope this helps.
