Ride on Water

[Hadeki]

I'm attempting to make it so the player can ride something across water. I can create a specific sprite myself, but I'm not sure how to go about making an event/script. I am planning to allow the player to mount something at any time, in any body of water (so terrain IDs may be very important) once they obtain a specific item.
Is there, like, a simple way to do this?

P.S.
I'm using XP, and Blizzard's caterpillar script (from Tons of Add-Ons) AND the Neo Mode 7 script.

http://creationasylum.net search for a vehicle script there

I searched that site as best I could for a few hours and I found nothing I could use.

Here's a vehicle script I found at RPG Revolution

Oooh. I fiddled with that and when I tried to customize it I just seemed to ruin it.
What I'm looking for is a script that allows the player to enter water from anywhere, not just one location where a vehicle is set.
Also, with that script it seems like the vehicle can only exist on one map and I need it to exist where ever water is (world map, towns, caves).
So... I tried to create some events that make it so when the hero is facing the water and presses the "C" button, they mount a whale thing and begin riding it across water, but that would mean I have to create an event on each square along the edge of all water throughout my game... Which is not very efficient.
