Water Traversal Troubles

Hi, this is my first time posting here, but I've seen before just how helpful these boards can be.

So, basically, my problem is this: I have a pool of water in a dungeon, and the player can board a lily-pad to traverse the water, but I can't seem to program how this is done. So for example, once you're on the lily-pad, by pressing UP, DOWN, LEFT, or RIGHT, you can move through the water in those directions. I think it has something to do with "through", but I can't find out what exactly.

How did you make that lily-pad? without seeing how you did this, we can't help you as there are too many options.

Usually the easiest way would be to use the boat vehicle for that and just exchange the sprite of the boat agains one of a lily pad.

So basically it (the event of the lily-pad, which is Below Characters and triggered by Player Touch) says,

@>Conditional Branch: The Left Button is being pressed
@>Set Move Route: Player
: :$>Through ON
: :$>Move Left
: :$>Through OFF
@>Set Move Route: This event (Wait)
: :$>Through ON
: :$>Move Left
: :$>Through OFF
@>
: Else
@>
: Branch End
@>

I tried the boat thing, but couldn't get the lily-pad sprite to be used as the replacement for the normal boat image. Also, since this takes place in a dungeon, I think it would look better if you could still see the player. I even tried to change the player sprite to the lily-pad and turn the event to the player so that it gives the illusion that you're moving your character, but you actually control the lily-pad. However, like the boat, I ran into the same problem where I couldn't use the lily-pad sprite as the character sprite.
