|As he appears in Goop's World 3: Shifted|
|Number of Games||7/8|
- "The boss is bound to promote us to lackey now!"
Moki makes his debut appearance in Goop's World, kidnapping Blossom to help King Grex attempt to rule the world. He and Shelldon are eventually defeated by Goop. He is one of the main villains of almost every Goop's World series game.
Moki is a victim of a Napoleon Complex; he is convinced that he is the single greatest Minion to ever live, despite the opposite being true. Moki is constantly scheming to get his boss King Grex to promote him to Lackey Rank, a dream which never seems to get accomplished. He's somewhat abusive to his cohort Shelldon, as he is convinced that Shelldon and Shelldon alone is the sole reason that their plans fail. While he isn't necessarily evil naturally, he follows his master loyally for his own selfish gain. He is also constantly annoyed at getting used as a ball.
Moki has no real special abilities to speak of, aside from building large machines to use against Goop.
In Goop GP, Moki can fire a sawblade that ricochets off walls before returning to the front of his kart.
In Goop's World 3: Shifted, Moki is given the ability to shape-shift by the Shift Sprites. He and Shelldon both use this power in Goop's Big Game Land, but they screw up, causing them to fuse together into Shellki, an enormous Moki/Shelldon hybrid.
A year after Goop arrives in the Gooptar Kingdom, Moki and Shelldon sneak into Blossom's Castle on Blossom's birthday, kidnap her, and steal her collection of Magic Opals for their master, King Grex. Goop then sets off to stop him. During the final battle, King Grex first watches the fight from the air while Moki and Shelldon fight Goop in the A.G.A.M.. After the ending credits, they are shown exiting the ruins of the castle before a large statue of King Grex falls on top of them.
One year later, King Grex, now a ghost, tears apart the Ethereal Veil, the plane seperating the Real World and the Spirit World. This causes the two realms to mash together, creating a Real World/Spirit World hybrid and transforming all of the characters into monstrous versions of themselves. When King Grex is defeated, Moki and Shelldon are shown bedding down for the night in the old ruins of Castle Grex.
Two years later, King Grex prepares to attack the Gooptar Kingdom with his army, only to have his army be attacked by an even more powerful army controlled by Dr. Oktor Von Derwiff. For the common good, Grex and Frogrump agree to temporarily team up with Goop, Bing, and Tawnya. Moki and Shelldon stay behind to watch after Castle Grex's ruins.
Two years after the events of Opal HQ, King Grex, now inhabiting a robotic body built by Moki & Shelldon, returns once more to exact revenge. He figures out that Goop's shape-shifting powers are why he keeps losing, so he enslaves a race of fairies called Shift Sprites, who have the ability to transform themselves and anybody else into anything. He then uses these new powers on his Minions. In Goop's Big Game Land, an amalgam of landmarks from previous Goop levels, Moki and Shelldon attempt to use their newly-found shape-shifting powers at the same time, causing them to fuse together into an enormous creature called Shellki.
Sometimes after Shifted, King Grex finds his army once again under attack by Dr. Derwiff, who has escaped The Vortex. King Grex sends his new recruits (Chomper, Chucky, Snerlin, and Springear) to defeat him. Moki and Shelldon serve as the Mission Control of the Minion Brigade.
