The water in the video is shader based, there are alot of tutorials out there for shader based 2D water so shouldn't be hard to find. If you are looking for sprite based animated water I'm not sure where to find one in this style.
Now I understand. Thank you so much.
Because I couldn't find the same tile set as in the image you created, and I couldn't find it anywhere else. It wasn't in the file you provided either.
But now I've managed to do it, and when combined with the shadows and waves in the image file, it fits perfectly.
