The fiftieth episode of Adventures of Sonic the Hedgehog, and the third part of the "Quest for the Chaos Emeralds" saga.
After a brief stop in Ancient Rome, Robotnik, Scratch and Grounder head for Ancient Mobegypt in search of the Chaos Emerald of Immortality. There, Robotnik makes himself a pharaoh, and enslaves everybody, including Sonic's Ancient Egyptian ancestor, Masonic.
This episode provides examples of:
- Be the Ball: After his mummified ancestor gives him an emerald that gives him a blue energy shield to protect him from Robotnik's immortality, Sonic, true to his video game counterpart, spins into a ball and has Masonic bounce him around the pyramid to attack Robotnik.
- Bowdlerize: The Toon Disney broadcast of this episode cuts out a scene where Scratch attempts to seduce Masonic.
- The Cameo: Miss Possum from "Magnificent Sonic" appears early in this episode as Sonic is surfing.
- Cool Board: Professor Caninestein invents a Time-warp Boogie Board so Sonic and Tails can follow Robotnik through time, this time with the proper time-spaces coordinates pre-set.
- "Eureka!" Moment: After Sonic disappears as the result of Masonic never meeting Penelope, a nervous Tails asks himself what Sonic would do. His answer is "Nothing. He doesn't exist now that Masonic never met Penelope.", which gives him the idea to play matchmaker.
- Extra! Extra! Read All About It!: At the beginning of this episode's second act, following Robotnik's takeover of Ancient Mobegypt, an Ancient Egyptian paper boy says this while handing out stone tablets informing people of that news.
- Fed to the Beast: Julius Robotnikus refuses to help Robotnik from being fed to the lions in his gladiator games.
- Heart Symbol: Masonic is surrounded by them when he meets Penelope at her chili dog stand.
- Immortality Inducer: The Chaos Emerald of Immortality allows its wielder to live forever, with the potential of recovering from harm and outliving everyone else. Robotnik and his ancestor are able to No-Sell Sonic's spin attack, but Sonic's ancestor gives him a necklace to counter this.
- Identical Grandson: Both Sonic and Robotnik's ancestors look and act very similar to their modern day counterparts.
- Losing Your Head: Grounder gets his head kicked off by a camel, and it lands on the table of a parrot vendor.
- Meet Cute: Scratch tries to pull this on Masonic by disguising himself as a cute girl to stop him from meeting Penelope.
- Mythology Gag:
- There are several references to Marble Zone from Sonic 1. Sonic and his friends push a cube-shaped stone into the lava and ride on it, and Scratch gets crushed by a chained weight that falls from the ceiling.
- The entrance to the burial chamber where the Chaos Emerald is hidden requires falling down a long tunnel and collecting enough rings to open the door at the end. This is a reference to the Special Stages of Sonic 2, which also required the players to collect rings to obtain the Chaos Emerald.
- Sonic's mummified ancestor gives Sonic an emerald that gives him a blue energy shield to protect him against Robotnik's immortality, a reference to the Single-Use Shield from the first two games.
- Near-Villain Victory: Sonic gets a chili dog at Peneleope's chili dog stand before Masonic, causing the latter to lose his patience, resulting in him never meeting his future wife and leading Sonic subject to being Ret-Gone. This is good news for Robotnik, as now his plan to collect the Chaos Emerald of Immortality can succeed without Sonic trying to stop him, but bad news for Tails, who takes it upon himself to play matchmaker.
- Nice Job Breaking It, Hero: Sonic accidentally erases himself from existence when he inadvertently prevents his ancestor from meeting his future wife.
- Pink Girl, Blue Boy: Like Sonic, Masonic is a male hedgehog with blue fur, while Penelope is a female hedgehog with pink fur.
- Ret-Gone: While in Ancient Mobegypt, Robotnik plots to erase Sonic's family history by ensuring that Masonic and Penelope never meet. He nearly succeeds when Sonic causes Masonic to lose his patience at Penelope's chili dog stand, which leads to Sonic disappearing as a result of Masonic never meeting his future bride.
- Rushmore Refacement: Robotnik has Sonic and his friends build him a sphinx with his face on it. At the end of the episode, Sonic refaces The Sphinx to have the faces of him and Tails.
- Shout-Out:
- The scene where Robotnik rides on Sonic's Time-warp Boogie Board features several references to Disney's Aladdin. Robotnik is standing on a flying carpet (though this carpet is merely covering up the Time-warp Boogie Board rather than being able to fly by itself), and he flies through a pile of camel dung (similar to how the palace guards chasing Aladdin land in a pile of fertilizer), as well as past a sword juggler (which is also one of the enemies featured in the Aladdin Sega Genesis game).
- The scene where Sonic races Robotnik to the Pyramid of Robotnikhotep is a reference to the chariot race in Ben-Hur, complete with Robotnik's chariot using spiked wheels to sabotage Sonic's chariot.
- So Last Season: Caninestein declares the Atomic Relativity Boots "yesterday's news", and offers Sonic a new time machine in the form of a chariot.
- Temporal Abortion: Dr. Robotnik travels back in time to Ancient Mobegypt and plots to erase Sonic's family history by ensuring that Sonic's Ancient Egyptian ancestor, Masonic, never meets Penelope, his future bride. He nearly succeeds when Sonic, who followed him through time to stop him causes Masonic to lose his patience at Penelope's chili dog stand, resulting in Sonic disappearing. It takes Tails to play matchmaker for Masonic and Penelope to get Sonic to return.
- Tickle Torture: Robotnik has Scratch tickle a pharoah's foot to get him to tell them which pyramid the Chaos Emerald of Immortality is buried in. When this doesn't work, Robotnik decides to make himself Pharaoh.
- Time Travel Episode: This episode is the third part of a four-episode arc involving time travel, and it involves an ancient pyramid.
- Watch Where You're Going!: Scratch and Grounder run into each other while deciphering the hieroglyphics revealing the location of the Chaos Emerald of Immortality.
- Who Wants to Live Forever?: Robotnik finds the Chaos Emerald of Immortality in his ancestor's pyramid. Said ancestor's animated mummy actually thanks Robotnik for taking the Emerald from him, as he couldn't bear to spend an eternity with Sonic's ancestor who was also in the tomb.
