I'm pretty sure these were both on YouTube, but I could be mistaken.

1. What looks like a university. There are Asian girls in uniforms running when a huge round mass of gelled substance ruptures, as the inside was still liquid. It may have been a monster jello, probably at least fifty feet across. They take some strapping or something off of it which was holding it together, but the inside was still un-set, so the whole thing began to let go with female university students running for safety.

2. Two European girls run down a path near trees or bushes, then abruptly turn to run into what first looks like a creek. To everyone's surprise, the 'creek' was a very shallow water flow over some nice deep, very dark mud. The two girls sink in, surprised that it wasn't water.

I had seen both of these a number of times, but can no longer locate them. I know the second one was in a foreign language, so searching for anything like 'jumping into mud' does nothing. Any help would be apprecitaed.
