Did you purchase Knockout? Was he given to you? Do his panels fall off like skin from a leper?! Well have no fear cause it's an easy fix.... The panels themselves have holes inside the pegs that fit within the leg. All you have to do is put a screw in there. You want the screw to be tight enough so that the panel isn't loosey goosey but just loose enough so that you can still rotate it for transformation. With one hole I found that the screw just drove itself in but the other needed a little cohersing. For this I just pulled the panel out and widened the hole slightly by rotating a blade on the inside edges of the upper portion of the hole. That's it! -Two left over screws -One screw driver -an x-acto And viola! Just make sure your screws aren't too long.
