I found a youtube clip from a movie. Don't know which one it is. I made a Gif of the messy part.!

Im 99% sure this is not part of a movie. The cutie is Olivia Phyland, from an australian tv show Studio 3 (just like a Nickelodeon show) and she did a lot of messy stuff recently. I mean she was pied and gunged a lot in the recent years!

Thanks Pinhead! I didn't recognize her for a minute!!

Awesome
