This is a very clever piece of precision work. The safety instructions for fitting the spring do require stressing, as I nearly cut my finger when releasing it. Maybe it could be fitted between the supports first, before cutting the tie, or supply it loose and unwound in a bag. This would also allow for easier coiling once secured. Also, the instructions did not detail each individual leg (one rear right handed, one rear left handed, one front right handed, and one front left handed), but I was able to ascertain which bit went where, as they are mirror images left to right, front or back, and they are different at the front. In addition, the instructions for the small brackets holding the flappy ears to the head were not clear, and I broke two before I realised, having to carefully glue and clamp them overnight to repair them successfully. Not withstanding those niggles, it is a fun project, and when it runs across the floor once built, it's quite amusing
