Jibmon is a slime Digimon based on a baby fish with a pacifier like device. Even though it is merely a Fresh level Digimon, it is worshiped and respected as if it were a Mega or Super Ultimate. The reason is very simple; It is the Fresh Stage of Cobaldramon, Hydra of Eclipse. The device around it's mouth is actually a more lesser version of the middle jaw seen on Cobaldramon's heads.
