Easter egg: On the Inspector Gadget 2 DVD, there is an optional main menu hidden. It is the IG2 logo at the top of the screen. If you press the up button while the words Scene Selection are highlighted the logo of IG2 will highlight. Then press Enter.
At the end of the movie, when Inspector Gadget gives an award to Penny he puts it around her neck and when the camera faces her, her hair is in the ribbon, but when they show her back it is out of the ribbon and then repeats itself about 3 times.
