Thanks everyone for the help. I like to method of simply moving the head
and then moving the last tail piece to position1, I'll implement that. I
also didn't realise I was cloning the same sprite, I thought I was creating
new ones so I obviously need to brush up on how to do that.
Your comments are much appreciated.
