For your original question:
> Have had my Pleo for 2 weeks now and he is still not walking or accepting his name
I assume it is a PleoRB.
If you are playing with it for a full battery cycle, every day for 2 week, it should be an adult by now. Once a juvenile/adult you can name it, but only if it is "in good shape" (well fed, proper mood etc)
The evolution for PleoRB is described here: http://www.aibohack.com/pleorb/tech3rb.htm
You can check the current evolution using statsRB or ProbeRB http://www.aibohack.com/pleorb/index.html
It will also tell you if your PleoRB is in "good shape" or "bad shape" to be renamed. PleoRB needs frequent feeding.
Good luck on the broken? neck.
