Dexter, tras caerse demasiado a causa de nueva forma y a pedido de su compañero Stan, investigó una solución para su problema al caminar y optó por aprender artes marciales, pero a causa de su sorpresiva sobrepeso y de su aspecto le es imposible ser aceptado por algún profesor; excepto una abuela de nombre Ragun. Ella empezó a darle técnicas de sumo solucionando varios problemas además de caminar, lo único que molesta a Dexter es que para caminar tendrá que sostener su enorme panza con los brazos inferiores.


Dexter, after falling too much because of his new form and request from his partner Stan, investigated a solution to his problem in walking and chose to learn martial arts, but because of his surprise appearance and overweight he can not be accepted by a teacher, except a grandmother named Ragun. She began to give sumo techniques solving various problems besides walking, the only thing that annoys Dexter is walking he will have to hold his huge belly with his lower arms.
