Ah, so you do like my work....there is a limit on what can be added into any Behaviour/Action and there is already a Behaviour out there for free for walking through water. If you add new textures you should also add new sounds for each one. Even if you have to use same name of the texture as existing one to keep same sound (if you don't want to add a new one).
Not sure why you would want to add sounds for some textures and not others....
It does work quite well, but nothing will cater for all individual requirements unfortunately.
