Andy is not made with linear joint zones. I never expected him to actually be used that way. Yes, I originally rigged him. So if you really want to play Stretch Armstrong with him do this ...

Select the body part you want to be stretchy

Open the Joint Editor [Ctrl]+[Shift]+J

Click on [Create Smooth Trans] then [OK]

Andy says, "I am Gumby!"

Rinse and repeat for any joints you wish to stretch.
