I will say a special Pleo Prayer and Native American Blessing for your Jimmy tonight before I go to bed, that he is healthy and running again as he should,
I do wish there were a Pleo HOspital where broken Pleos could go to get Healed. Someday perhaps there will, I am allso hoping that someone here on this site may have a clue or suggestion on what you can do to fix jimmy. It would be easier if there were perhaps someone in your town that knows how to work on Robots and could take Jimmy apart and look at his motor and find the problem as it sounds like an internal problem that can only be fixed from the inside. HOw long has Jimmy had this Stuttering or loud sound? Is it old or recent? This may give a clue to what the problem is.
I know how bad I felt when NOva broke her neck and she also limps, but I love her all the more but she still works even with these problems, We are all wishing Jimmy and you success with fixing his problem, I will do my best Native American Blessings for help for Jimmy tonight, but I have never done one for a Robot ( non living being) before, but Pleos are as close to being alive as anything inanimate that I have seen before. Have faith Franziska that Jimmy will get better and we are here to support you in this sad event. You have many Pleo parents and friends alike here.

Sending you and Jimmy HUGE HUGE HUGS AND KISSES FOR HEALTH!
