- This is probably the first time in the Scooby-Doo franchise where an episode makes a reference to a real social issue: drugs. This was a national crisis during the 80's and many cartoons during that time had been discussing it. When this episode aired, Nancy Reagan's Just Say No campaign was prevalent; this campaign from the 1980s and early 1990s was part of the U.S. War on Drugs and it was used to discourage children from engaging in illegal recreational drug use.
- Because of this, in the UK, Cartoonito skips over this episode, although it does air the episode of Baby Looney Tunes, Who Said That?!, where Daffy learns a bad word.
- The title of the episode is a play on the main character's name: Scooby-Doo.
- When Daphne suspects Sandy Sneakers to be behind the case, she was right. However, this is one of the few episodes where multiple suspects are guilty. Also, she is one of the few suspects not to wear a monster costume.
Animation mistakes and/or technical glitches
- When Daphne and Velma are examining Al's trophies, Velma's lips are moving, but Daphne's voice is heard reading the inscription.
Inconstitencies/continuity errors and/or goofs/oddities
- In the beginning of the episode Red Herring gets pinched by a lobster after scaring Scooby and the gang. The lobster is bright red. Lobsters acquire their red color after being boiled. Live lobsters are actually a dark greenish-brown color.
- There is no explanation for the origin of the Headless Skateboarder. Presumably this was the first time such a villain appeared, and as such this would be the beginning (and end) of the Headless Skateboarder.
