Retard Mario is Mario's retarded counterpart and a guest character in the SuperMarioLogan franchise (particularly Mario and Luigi's stupid and dumb adventures and an SLL Shorts, Retard Mario Gets Arrested).
This version of Mario plush is from Kellytoy.
In SLL Short: Retard Mario Gets Arrested, he reappears and spends most of his time making weird noises, dancing, and touching people. This spooked a large Goomba and Mario. Mario then called the cops and sent him to jail. When he was in his jail cell, he was freaking out as if he was scared. After this event, we never saw Retard Mario again until Mario Plush Collection!.
- He is somewhat similar to the SMG4 variant of Mario due to him also being retarded and based off his Super Mario 64 appearance.
- The other reason for being an SMG4 Variant is the fact that there's a spaghetti with meatballs, with said image appearing in most SMG4 videos.
