Just for fun, here is a King Brain Coral that uses two displaceable spheres and a system to get power fractals to show bilateral symmetry.
The terrain uses a Heightfield erode so you need to click the erode now inside that node to get the Brain King sitting on his sand bar.
Two example renders one with negative displacement on the light color and one with positive.
For the bilateral symmetry to show up the texture of each sphere needs to be centered on its own sphere object.
Where ever you may move them to, you need to copy the spheres location coordinates and paste them into the texture's transform input shaders.
