You can, but it slows down Graal terribly whenever you use a bunch. And because you'll most likely use a lot.. ya, it's not advised. I posted a suggestion a while back for something that would make tiles animate without slowing it down, but it didn't go anywhere.
You can however, script it to animate, via placing all the animations on the tileset and scripting it to change the tile between the other animated tiles, like how the flowers are done.
