Steven Universe: Marble Madness is the episode that sets up the final battle. After what happens in this episode you know that the finale will be awesome. The plot of this episode is that Peridot's marble robots return to earth for unknown and this time they are 10 feet tall. One of my favorite things about this episode is how Steven proves that by being open minded you can actually get something done. Steven also has some really funny lines in this episode. It is also worth mentioning that on the week of March 9th we will get 1 new Steven every day until thursday when we get a special half hour episode. I give this episode 5 out of 5 stars By Nick Starceski.
