Well I take him out of the terrarium and place him over my shoulders/around my neck. At first, he'll usually wrap himself around my neck and hang out. Usually, within a few minutes he'll start moving around trying to find a way to get down...moving over to my other shoulder, slithering down my shirt...he'd actually fall if I didn't hold onto him. He will stay on longer if I'm standing. If I sit down, he'll usually almost immediately start trying to slither away onto whatever surface he can find. I always support his body properly, never holding him dangling or anything...I'm just not sure what the problem is!
