Sonia, LEGO® Customer ServiceWe’re happy to hear you had fun building this set! If your set seems like it's not very sturdy, the best thing to do is double-check your build. Sometimes there may be a piece just a little off from where it should be. You’ll also want to make sure that all the pieces are pressed tightly together. This should help you perform real stunts!
