Snow Port Tileset Animations

I’m designing a chapter set in a snowy port town where the characters have to board a ship to escape. In the repo, there’s a snow village tileset which should, in theory, work perfectly for this. Unfortunately, the required map animations seem to be missing. Does anyone know where I can find them? I’d hate to have to do something lame like use the generic village tileset and come up with some BS excuse like “summer has arrived and the snow has melted” or the like.
