A zone brick is basically the same as a water brick
Someone told me that there is a water bricks which can be built inside a zonebrick
The only way to currently do this is to create normal bricks and then event them to be water bricks.
Need to keep brickcount low :/
Use baseplates. You can use zone events to make the area underneath them swimable.
you can build inside water bricks and you can build water bricks inside normal bricks (as long as they're showing)there's nothing needed for it
