Leftmost side of the image, middle plant. The one that is stacked into a square tower.

Thank you! I found it from a link when searching for that name:
Crassula socialis
Best

 

Looks like Crassula perforata to me.

There you go! Cool, thanks so much!

 

definitely c. perforata.

it needs full sun to keep the compact shape - will get leggy/stretched out if not in proper light.
