Unnecessary Turtle did Mario plush videos, live streams, and gaming. He had another channel called "Tendonno" with all of his videos deleted.
Unnecessary Turtle mainly made videos of Minecraft. However they all got deleted because they were embarrassing to him. As of 2017, the oldest video accessible on his main YouTube channel (using the Wayback Machine) is his old channel trailer. There is a YouTube channel called "Unnecessary Turtle Archive" which has a lot of his older videos but none of them were from April 2016-June 2016.
