[Map] How To Edit Water Animation

I have been attempting to edit the watertiles in a romhack I'm working on. However it doesn't seem that the tiles for the sea animation is contained inside the tilesets. It is also not stored together with the flower and grass animations, If someone could direct me too either a way to edit this, or an offset to find it using existing tools that would be greatly appreciated.

(As a sidenote, I have also been looking for ways to create custom tile animations, if anyone has a link to any existing documentation regarding that that would also be awesome).

Assuming you know how to use/have already used Tileset Animation Editor (otherwise go here) water animation tile are in Animation 1 of Tileset 0 (For Emerald at least).

edit:

Nevermind, it is working wonderfully, I appreciate the help.
