The GoAnimate version of Mario's voice is Paul, but it switches to Jennifer when he's crying. He is an epic troublemaker and he cries whenever he gets grounded or something goes wrong. His friends are Caillou, Sonic, Yuko Asou, and Mega Man, and he gets grounded by Peach a lot. At his school, Dr. Robotnik is his principle. Hair Caillou is his ultimate enemy due to being a Gary Stu and never getting punished, but he always finds a way to get back at him.
