its more of a solid bump than a rocky one and the lower half is definatley not paralyzed cause he likes to coil pretty tught around my arm with his lower half. I adopted him on saturday from forgotten friends reptile rescue in lancaster county, pennsylvania. He has 2 more adult bps if anybodys interested, they were in good shape and looked to be a good size and mine had an awesome feeding response the next day i got him. He is also very well tempered and very good around the kids.
