Scarab dares the Mummies to face him in the Challenge of the Maze. This is an ancient challenge where the winner gets the right to be the Pharaoh's protector. The Mummies faced a lot of these challenges in the past and had never lost. No magic is allowed, but Scarab uses the ""magic of technology"" to aid him. First he defeats Rath with a powerful magnet. Then he defeats Armon by tricking him into the path of a subway train. He defeats Nefer-Tina by temporarily blinding her. He tries to use projectors to decoy Ja-Kal, but Presley clues Ja-Kal in and Ja-Kal defeats Scarab.

Ja-Kal contemplates about Kimas, about his own son, and about his duty. Rath realizes that if they destroy Arakh's scorpion charm, then Arakh's scorpion suit will be sent back through the Western Gate forever, taking Arakh with it. But Arakh had lost the scorpion charm at the museum exhibit, and the exhibit was being taken away in a truck. The Mummies catch up to the truck just as Scarab in his helicopter also reaches it. The helicopter takes the exhibit crashing back to Scarab's lair due to Heka's inexpert flying. Arakh finds his charm. The Mummies meet with Kimas at Beefy Burger. Kimas leads Ja-Kal into a trap at Fort Point, but finds out that his own father was the one lying. Kimas defends Ja-Kal from Arakh and destroys the charm sending himself and Arakh back through the Western Gate.

In a clever plot by Scarab, Pharoah Amenhotep I comes back in spirit form. When Presley and the other Mummies are fooled by the spirit, it is up to Jakal to pull the wrapping off their eyes.

Scarab now calls forth Kimas' spirit. Heka tells Kimas about the modern world and he takes a skateboard and goes out to explore. Nefer-Tina and Armon see Kimas in trouble, but he easily mummyhandles the bunch of goons attacking him. Not knowing who he is, Nefer-Tina and Armon take Kimas first, to Beefy Burger, and then to a dance hall. Scarab and his Shabti attack, and Nefer-Tina and Armon learn that Kimas is a mummy and teach him to transform. They escape in the Hot-Ra and are chased down Lombard Street. In the battle Kimas nails Scarab. Ja-Kal and Kimas finally reunite, but Ja-Kal is extremely cautious and won't take Kimas back with them yet. Kimas goes back to Scarab and tells him how he just about had the Mummies' trust.

When snoopy classmate Elaine tries to discover Presley's secret, Presley and the Mummies must fight off Scarab, save Elaine, and still keep their secret under wraps.

When Scarab tries to obtain the Spirit of Pharaoh, Presley and ancient Prince Rapses do the time warp and trade places. The Mummies must set things straight before Scarab catches on.

Scarab summons Nuhn who starts drying up the city's water supply. With the city out of water, Scarab is able to sell water at $100 a bottle and bring in lots of cash. The Mummies put Kahti in one of the bottles to lead them to Scarab. Finally, they drive out to Death Valley with Nuhn following. Can you say ""evaporation""?

Nefer-Tina wishes on a star for someone to love her. Somehow that wish brings Apep back through the Western Gate. He is in the same human form known as Pep as he was in Desert Chic, and again wants Nefer-Tina to be his queen. Nefer-Tina still has her affection for Apep, but says she is sworn to protect Rapses. Apep then delivers Presley to Scarab, with the hope of double-crossing Scarab in order to please Nefer-Tina. But things do not go as they should and Apep again has to undo what he has done.

A new exhibit is featured at the museum. Two mummy cases are included, and the Mummies note that one is labeled ""Kimas"" and the other ""Scorpion"". When Ja-Kal opens a case, Set and Anubis attack him. They were stealing the mummies and the sarcophoguses for Scarab. They escape, and head back to Scarab's lair. Scarab, Set, and Anubis summon the ""Scorpion of the Desert"" from beyond the Western Gate. The spirit of Arakh, Ja-Kal's brother returns. Ja-Kal recalls back to when Amenhotep made Arakh his spear bearer. Ja-Kal had saved his life from a lion, but Arakh was bitter and made jealous when Ja-Kal was made the leader of the Royal Hunt. Ja-Kal continues recalling how Arakh helped Scarab defeat them to kill Prince Rapses. Ja-Kal and Arakh have their first big confrontation in the museum.

The show begins with the Mummies in battle with Scarab and his Shabti. After the battle, they find themselves far away from their Sphinx needing to re-energize. Without any power left to transform, they have to cross town on foot and have many interesting close-encounters with various city people. This show is notable in that Presley does not make an appearance.

Presley and the Mummies go on a tour of Alcatraz. Armon takes a side trip to the dining hall and the Mummies and Presley lose the group. Scarab uses Shabti to make the tour guide believe everyone is back on the tour boat, and the boat leaves. Ja-Kal becomes separated from the others and Scarab locks him in a prison cell. Scarab brings forth the prison spirits to go after Rapses for him. Escaping the spirits, the other Mummies see Ja-Kal in the cell and bust him out. A giant firebird - the evil spirit of the island then goes after them.

Rath is trying an incantation to invoke the power of a Talisman (a bug-like amulet). Rath translated the incantation incorrectly into: ""By the spirit that guides us all, make me as the beetle strong"" and it does not work. When Armon reads it, he says it correctly where the last word is ""small"" and not ""strong"". Instantly all four Mummies shrink to the size of cockroaches. In their quest to reverse the spell, Ja-Kal gets swatted by Presley; Nefer-Tina almost gets swallowed by Presley; and Armon gets stepped on by him. Kahti tries to eat the Mummies and swats Nefer-Tina and Armon. When Kahti finally recognizes them she gives Rath a big lick. Charlie, the janitor, mops them up. Armon and Ja-Kal end up in the mop pail. Rath and Nefer-Tina get attacked by a spider. Armon gets stuck in Charlie's pocket. Rath and Nefer-Tina make a flight on a paper airplane.

Presley's father arrives unexpectedly for the weekend. Presley is delighted to see him. Presley's father is not the most honorable man. He secretly picks up a rock and gives it to Presley calling it a magic rock to ward off evil spirits. He takes Presley to the amusement park and cheats to help Presley ring the bell. He continuously lies about the great expeditions and battles he's been involved in. But worst of all, he steals the museum's Crown of Ramses the Great, to sell to Scarab. When he admits to Presley that he stole it, Presley is crushed, but Nefer-Tina chears Presley up. ""Whoever acquires the Crown develops unimaginable powers."" Scarab puts the Crown on and becomes huge and all-powerful. When Presley's dad helps the Mummies try to defeat the huge Scarab, Presley regains his faith in his dad. They make up, and his dad takes his leave.

A strange series of earthquakes take place, emanating from the Twin Peaks Park. The Mummies and Presley go there and find it is Geb, the Spirit of the Earth, who is saddened because he and his wife Net, the Spirit of the Sky, are in the midst of bad husband-wife fight. The Mummies try to help get them together again. Ja-Kal suggests he gives Net a bird as a present. Nefer-Tina tells him to give her a flower. Rath suggests words of poetry. And Armon sculpts Geb's body to try to make him irresistable. Those don't work, so the Mummies try to appeal to Net and she brushes them off. Finally, they vacuum up Net and give her back to Geb where they make up ... for a while anyway.

Scarab has his Shabti trying to recast Talos at the City Junk Yard, but the Mummies destroy that operation. Rath takes some of the magical material, and back at the Sphinx creates his own 12 inch tall Talos. It obeys their every command. Presley sneaks away with the miniature Talos, and uses it to clean his room for him. Talos gets hit on the head and remembers who he is. He breaks out of Presley's house and starts absorbing metal from everywhere and growing. The Mummies catch up with the now huge Talos at a construction site. Talos gets defeated again ... for the time being.

Scarab decides to try to get rid of Ja-Kal. By doing so, he figures the Mummies without their leader will fall into disarray. Scarab uses a ceramic falcon idol to attack Ja-Kal's animal sign. Scarab's plan starts to work when Ja-Kal takes off and ""the three stooges"" fight for leadership. Meanwhile, a public costume ball called ""the Night of the Living Dance"" is taking place at the Youth Center. Presley is dressed as Frankenstein. Elaine is a superb hunchback. Walter is a werewolf. Cynthia is dressed as Frankenstein's bride (but Presley still makes no progress with her), Presley's mom is a witch, and Mr. Huxley is the Creature from the Black Lagoon. Mr. Huxley gets to dance with Nefer-Tina. Armon spends most of the night eating all the food at the dance.

The ghosts of gold-rush miners are accidentally invoked by Scarab.

Chontra returns. She makes a deal with Scarab to bring Presley to him in exchange for some of the eternal life in the Prince's spirit. Chontra transforms into a young girl, calling herself Cheryl, and makes sure that Presley becomes interested in her. This is not to Elaine's liking. Meanwhile, the Mummies spend most of the show acting as service people so they can watch over Presley's mother.

Nefertina, frustrated by lack of respect, falls in love with a charming biker who in truth is the snake demon Apep, who is looking to take revenge on the family of 'boy prince.'

An amnesiac Rath must swallow his pride and depend on the help of homeless strangers to survive. Meanwhile, Scarab ""drains the years"" out of the homeless in order to extend his own life.

Scarab makes a potion to make him look young and handsome. The potion accidentally ends up on Nefer-Tina, and turns her beautiful. ""Wow, she looks 3000 years younger"", Armon says. Nefer-Tina goes to a nightclub. Everyone is amazed by her beauty. A girl from the Fad modelling agency is there, and almost overnight Nefer-Tina becomes a fashion marvel. She appears in fashion shows, on magazine covers, and is interviewed on ""Lifestyles of the Inexplicably Famous"". Scarab disguises himself as a photographer to go after her, and calls himself Ray Sphinx with ""Vague Magazine"".

Mr. Huxley and his class (including Presley) are touring the Fisherman's Wharf. Chontra terrifies them with spirits and leaves a cat statue that the Mummies take back to their Sphinx. Chontra uses the statue as a gateway to get to the Sphinx. Her goal is revenge on Rath, so she distracts the other Mummies by changing into people in their thoughts. Ja-Kal thinks back to his wife Tia and their baby son, and Chontra becomes Tia. For Armon, she changes into his mother and brings him food. She then becomes Nefer-Tina's friend Kenna, who never knew she was a girl. With those three out of the way, she changes into Ja-Kal to fool Presley and ready herself for the final battle with Rath. But what is Chontra really? At the end of the show she taunts Rath with: ""You can't face what I really am"", and she then becomes Medusa.
