pastel with head wobble

now i know that this is quite common with spiders, but pastels ? i noticed my pastel doing the head wobble every now and again, but recently since i have way too much time on my hands ive been noticing it more and more... is this common ???

Common?....no..... possible?....sure.

my pastel sometimes shows a glimpse of a minor wobble...might jus be off balance

oh... i suppose its just one of those little quirks that makes him special ! :D
