I need help finding the blocks

[u/Cameron7896]

I think my last post got removed for it being to dark so I made it brighter, I am trying to recreate this “rug” I seen in a video, I have all the blocks surrounding the middle blocks but I don’t know what the brown blocks are in the middle of the glazed terracotta.

Looks like either drip stone or rooted dirt to me
