Sandy's Rocket provides examples of:
- Abnormal Ammo: Sandy's collecting guns, which shoot nets to capture samples. SpongeBob and Patrick use it to trap "aliens".
- Accidental Murder: Implied to be the case with the "whirlybird" incident.
- Black Comedy: SpongeBob apparently has killed a lot of people during the "mishap with [Sandy's] whirlybird", judging on the size of the graveyard she shows him.
- Boomerang Bigot: Patrick, when he believes he's an alien.
- The Ditz: Patrick. He holds the gun backwards, causing him to trap himself instead of Spongebob.
- Early-Bird Cameo: Flatts appears amongst the people kidnapped by Spongebob and Patrick.
- Eldritch Abomination: What SpongeBob and Patrick see everyone in Bikini Bottom after they crashland the ship.
- Feelies: This episode and Squeaky Boots had specific scratch and sniff stickers released by Burger King to promote Rugrats in Paris, which also used the scratch and sniff gimmick. The smell involved included the scenes where Patrick gets toothpaste in SpongeBob's peanut butter and when SpongeBob pulls out Squidward's hot water bottle. Ironically, the symbol used to signify when to scratch and sniff was accidentally left in the episode until 2002, three years after the stickers were discontinued.
- Mistaken for Aliens: SpongeBob and Patrick think their friends are aliens and start capturing them. In the end, each thinks the other is an alien as well.
- Platonic Cave: SpongeBob thinks this is why the moon looks just like Bikini Bottom. "The aliens must be projecting our thoughts into the environment."
- Shout-Out: Spongebob saying "Hey, you got toothpaste in my peanut butter" is a reference to the original Reese's Peanut Butter Cups commercial.
- They Look Like Us Now: What SpongeBob and Patrick assume when they see all their friends on what they think is the moon.
- Vocal Dissonance: SpongeBob gets a deep voice when he says "Put me in the brig, I don't mind!"
- Wrong Turn at Albuquerque: The rocket actually missed the moon and landed back on Bikini Bottom, but SpongeBob and Patrick don't know that.
