George Avocados mentions how the gang is responsible for destroying his ranch, which happens back in "Scarebear".
It is revealed through a flashback that it was Friar Serra who placed the 4th piece of the Planispheric Disk inside the wheel of cheese that was in the hands of Gene Shepherd, the owner of the Travelling Cabinet of Curiosities.
Friar Serra: You are all still in danger. The story of Crystal Cove is a lie. The donkey never tried to save the town, but to destroy it. There were four of us and Porto in the Fraternum House Mysterium, a group of mystery solving friars... We encountered a Conquistador. He told us a tale of great evil before the madness got the best of him, and he vanished in the night, leaving behind two ornimated disc pieces... We quickly became obsessed with the pieces. We realized there was an evil at work... we attempted to destroy the pieces to rid us and the town of evil, but the evil did not allow us. The evil manipulated Porto... Porto set out to destroy the town... I chased Porto to the alligator infested swamps, outside of town... Porto was dragged by the alligators, but not before I was able to retrieve the piece he took... The other piece, thankfully was lost to the bottom of the ocean when Crystal Cove sank into the sea. It was up to me now, to hide the last piece... Beware, Nibiru is coming. This has all happened before, it begins with the animal. Always the animal. Heed the warning of the alligators! The Dog Dies! (Friar Serra's corpse crumbles to dust)
Scooby-Doo: The dog dies, is he talking about me?!
This episode reveals that the diamond stolen by Theodore Avocados was never recovered, in spite of what Mayor Jones said in the end of the episode The Secret Of The Ghost Rig, that its recovery would make up for the revenue stream lost because of the exposure of the Ghost Truck as a fake. A possible reason for this happening, was that he was most likely lying for his own political advantage, since they did not find the diamond.
The flashback shows Porto pushing barrels marked "TNT," into the caves. This is an anachronism since that explosive was only invented in the end of 19th century.
This marks thesecondappearence ofVincent Van Ghoul in person in this series.
Vincent Van Ghoul's introduction to the theater production of Crystal Cove's history was in the same tone of Vincent Price's "rap" in Michael Jackson's Thriller video.
