But that’s kind of what I’m looking for, permanent products.

Yeah, but they teach them to do that outside the water, in environments specially made so they have no issue with it. I mean modes of expressive artistry that can be done while under the water, in their natural niche. Think, what can you teach a dolphin that they can take with them back to the wild and maybe teach to younger dolphins?

I’m sure, for example, if there were crops that grew underwater, they could make their own crop circles.
