Do juvenile scorpions burrow when they sleep?

I just got my 3i asian forest scorpion. and its enclosure only had one rock for its main hide, and two pebbles to support it. it stayed there the whole time. the next day i couldn't find it anywhere else. i tried checking underneath the substrate--none. i dont think theres a chance he could've climbed his way out tho.

At that size, they will burrow as deep as possible. They are a species notorious fr digging.

Have a picture of your enclosure setup?

Gotta be careful of using rocks for young scorpions such as 3.instar..
