- 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 this, she was right. However, she was not the monster nor she was alone.
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.
- How does Velma know this much about drugs that she can recognize them at first glance? Perhaps she's that smart.
