Keith, Customer ServiceOh no! I'm sorry your son is having some trouble keeping his new Monastery of Spinjitzu together. We always test and retest our toys to make sure that they’ll stick together and hold up to play when they’re built as shown in the instructions. Since his set seems like it's not very sturdy, you might want to double-check his build. Even the best builders sometimes place a piece just a little off from where it should be, which can start to cause problems with stability. You’ll also want to make sure that all the pieces are pressed tightly together. If you'd like some help looking over the build, or if you find that any pieces aren't sticking together as they ought to be, please get in touch at LEGO.build/Service.
