Ghouls are a race of zombie-like beings in Ninjago, in which most of them were travelers that went to the Pyramid of the Sphinx.
History
The Maze of the Sphinx (flashback)
Shezada, Wu, and Garmadon encountered hordes of ghouls in the chamber preceding the Sphinx's chamber, forcing them to fight against the mindless creatures. Believing the right way to have be through one of the tunnels from which the ghouls emerged, Shezada and Garmadon ran atop the shoulders of the ghouls pouring from the tunnel on the right side of the room, making their way past them before turning back for Wu who had been left behind. On the way back, Shezada was caught off guard and bitten by one of the ghouls, though she brushed off the injuries as unimportant.
Seconds after opening the Sphinx's chamber however, Shezada's infection began to take effect as her skin turned a sickly gray and the whites of her eyes turned pure black, beginning the process of transforming into a ghoul. Fortunately, Garmadon used the group's wish granted to them by the Sphinx to restore Shezada to normal.
Official description
Loud, slow, and smelly, but extremely dangerous, a ghoul preys on other living creatures. A person bitten by a ghoul from the Sphinx’s pyramid turns into a ghoul themselves.
