"In the Ninjago cartoon series, this dragon is named Grief-Bringer, which turns out to be an appropriate name for this model. The build experience and detail on the model are both great; however, the issue is the construction of the front legs - and how that construction affects ability to play.
The front leg joints - specifically those at the ankle and knee locations - do not support the weight of the model (At least, I would call them the knee and ankle joints - dragon anatomy is not my area of expertise). These joints are the smooth ball-and-socket type joints, which do not lend themselves to stability with the weight of the dragon. Unless perfectly poised, Grief-Bringer tends to fall forward on his face (snout). This is in contrast to the click-type of joint, as used on the hind legs at the hip joint. There have been no issues with these joints and the rear legs.
The front leg and wing assemblies also tend to fall off if the model is handled too much. It looks like the root cause of this issue is the fact that the front leg and wing sub-assemblies are joined to the body with two short rods, which do not snap or lock into place. I have needed to re-build this model enough times that my son is hesitant to even play with it anymore; it has become a display piece."
