CMRB, also known as Cartoon Made Rap Battles, is a Cartoon rap battles series created by Zara and co-owned with LittleFlecks. It shares similarities to Matthew’s Thomas: Epic Rap Battles of Cartoons (ERBOC) in a cartoon rap battle sense. Started on July 19, 2014, and would be discontinued around Jun 17, 2020 (In a post by the owners of CMRB in FRB Discord). While CMRB temporarily returned with Phineas and Ferb vs. Dexter and Freddy Fazbear vs. Cartman (being the last battle), the original owner, Zara, would leave the channel, leaving Flecks to be the only one with access.
