Exploring an Abandoned Temple!

We found an abandoned temple here in Phang Nga Thailand. We stumbled upon it by just driving past it and thought to go have a look. There were odd things that we found here the caves. What was particularly interesting was the buddha's made from mud and hair. We attempted searching online about what it was but cannot seem to find any information regarding it. If you know what it could possibly be, please mention so in the comments!
