User blog:ImetNickJr/Nick and Jr. Meet Mario

I'm not sure if any of you remember, but when I was young, there was this mini Youtube series called "Nick and Jr. Meet Mario". It had 3 parts in the whole series. It was on Youtube between 2009 and 2013. Then, somewhere in 2013, the videos were gone. I'd like if someone could tell me if they were deleted or if a copyright issue brought it down. Cause, by the looks of it, the videos may never see light again.
