So this little magical piece of animation surfaced back in February. It was put out by Metro Trains of Australia in efforts to educate their population on train safety. Basically you wouldn't poke a stick at a grizzly bear, so you also shouldn't try to beat the rail crossing gates. This Dumb Ways to Die: What was meant as a public safety announcement turned into a viral animation sensation. Mixing a catchy tune with cute little blobs getting killed and a serious message at the end, how could it not? They even have an app for iOS and Android!
Enjoy! And be safe around trains!
