Thanks to Tegan713 for passing these along. Molly Roloff apparently has a You Tube channel (one would assume -- mojoro2...aka MOlly JO ROloff). It's not clear if these were school projects or their idea of entertainment, but there are two videos.
The first one primarily features Molly and her friends Sarah and Paige. The credits say Zach filmed and Jeremy did the editing. Jeremy, Jacob Roloff, Mueller and Zach's girlfriend Tori are in the video briefly as "the rescue crew". It's filmed on the farm and in Matt's office. They named the 'doctor', "Doctor Hemp".
The 2nd video was previously, briefly, on Jeremy's channel but he deleted it once people began commenting on the part where it looks like the Roloff friend tries to give Rocky a little shove off the hill -- and that set off comments about the Roloffs animal abuse and treatment of cats -- then Jeremy deleted it. But this is the same video. It's basically 2 minutes of their friend Christian running around Roloff Farm. Jacob Roloff is a bystander watching.
This will illustrate between our site and the official Roloff sites. If you're wondering who Christian is, if you read Amy's official Facebook fan page, Christian is the polite young man who was playing with Jacob in the Roloff pool (Amy posted the picture). A great kid.
If you read our site, you'll best remember Christian as the underage friend (around Molly's age) who was doing shots of Jack Daniels in the Roloff garage with Jeremy, Zach, and Mueller in the video by the french girls -- it was removed shortly after we posted about it.
