Revealing mistake: Scooby knocks on a trunk and it knocks back. Fred is shown and tells Scooby to open it. But in that shot, Fred's face is so badly drawn, you almost can't even tell it's him if not for the clothes and the voice. (00:05:20)
Continuity mistake: The Ape Man breaks the rope bridge that Scooby is on and it begins to fall. But by the Ape Man, the stakes holding the broken ropes are still in the ground at his feet. Scooby falls down and lands on a root, which bounces him back up where he punches the Ape Man. The stakes and broken rope have vanished. (00:03:50)
Continuity mistake: The camera pans over the filming set and stops on the gang with Mr. Maxwell. There is a van behind them with the Ape Man movie poster on the side. The vinyl piece on the side of the van goes behind the poster and is lined up directly with the orange letters saying "EPI-CENTER FILM COMPANY." It then cuts to a close up of the poster and suddenly it has moved up on the vinyl and become smaller, lined up with the underside of "LOCATION No.2" (00:01:20)
Plot hole: Given he fell down into a ravine it seems impossible for Carl to have got back to his trailer before Mystery Inc does.
Audio problem: Shaggy and Scooby are walking around trying to find the Ape Man to lure him into the trap. There is a sound and Shaggy says "What's that noise?" It cuts to Scooby who is following him who says "RI ron't row." But his mouth does not move at all when he says this. (00:14:15)
Continuity mistake: The Ape Man puts on a mask of Scooby and pretends to be a reflection. As he is mimicking Scooby's movements, he places his hand to Scooby's and his nails are sticking up. It cuts to a different angle and his hand is in a slightly different position, and his nails vanish. (00:10:05)

Answer: During most episodes of "Scooby Doo, Where Are You?," the gang often split up to explore the latest haunted mansion or abandoned windmill or deserted amusement park. Scooby and Shaggy would generally end up together, Velma would often go off alone, and Daphne would frequently go exploring with Fred. It seemed to be a running theme in the "Scooby Doo" cartoons that Daphne was perpetually flirting with Fred. Fred, however, always seemed much more obliviously preoccupied with finding the next clue, foiling Daphne's amorous intentions. I have always been under the impression that the Scooby-Doo gang was a pretty sexually ambiguous group. More than a few people have suggested that athletic, well-coiffed, ascot-wearing Fred, and bookish Velma were early archetypes of gay/lesbian teens. The show existed in a time when several cartoons suggested sexual ambiguity in its characters: Effete Snagglepuss, a repeatedly drag-wearing Bugs Bunny (who even appeared in TV's first same-sex wedding with phallic rifle-toting Elmer Fudd), prim and polite gophers Mac and Tosh, Peppermint Patty, Marcie, Schroeder and Linus from the "Peanuts" cartoons. But whether or not any then subversive homosexual undertones were ever intended in any of the characters, the oft-paired Daphne and Fred never seemed able to get their relationship beyond the lukewarm stage, much to Daphne's apparent chagrin.
