Haha, can't believe I haven't seen this earlier! Though it's not as simple as the original whistle animation, it's just as good, if not better. The way the whistles all gain a life of their own and go out on a venture to punish and hand out judgement, and the portal characters all get involved, it just brings in a lot of nostalgia in the movie. Great music and great animation to go with it, and a theme that really brings me back. Keep it going!
