Any guesses what this stitch is?

Hello fellow knitters, I am making my daughter a doll and came across this knitted doll hair that I’d love to incorporate. I can’t tell though how its done. It doesn’t look like individual bobbles and neither like chinese knots or knitted buttons, it looks a lot more haphazard and inconsistent than those. It may be crocheted or finger knitted and then sewn to the dolls head but I’ve tried a few things and can’t seem to be able to replicate. Any ideas?

I figured it out! It’s hand knotting, how clever!

That is clever! I say videos on making curls but nothing close to your photo. Glad you figured it out.
