I want to create the feeling of a fluffy marine creature.

I followed a tutorial to do it, but after adjusting the Displace weight, it became different from the tutorial. I want to change from the first picture to the second one. Please help me. Thank you very much.

This has to little context. We won’t be able to help.
Reference the tutorial you used, tell us which parameters you changed. Also, it looks like you already managed to create the second image, so what are you missing?
