Mario Saves Someone "Part 1" was an extremely early episode of SuperMarioLogan. It has an unofficial sequel in Yoshi Takes Mario to McDonald's. The episode was done in a single take, it is a completely un-edited video.
Mario is looking at a coin from a limited edition Super Mario Galaxy game when Yoshi yells for help. Yoshi is stuck on top of a huge tower of video games after he tried to get a banana. Mario saves Yoshi, and Yoshi eats Mario's coin, making Mario very sad.
