- Awesome Music: Dry Cereal has the Car Chase, which is a really awesome song but gets mostly drowned about because of all the noise the car makes. And most of the Operation Ozone tracks found on the bowling alley's jukebox which can be played on a CD player as the game disc doubles as an audio CD.
- Broken Base: Which English version is better? The Get Smart-styled original or the James Bond-styled British dub?
- Do Not Do This Cool Thing
- In Some Assembly Required, Fox has to make a fake ID to get into a restricted area. Before doing so, he reminds the player that only spies can make fake ID's and only when they're on a case.
- In Operation: Ozone, he finds agent Roger Boar hiding in a medicine cabinet, but remarks that it's normally not polite to look in other people's medicine cabinets and that he's only doing it because he's a spy on a case.
- Foe Yay: Russian Blue, William the Kid's dragon, openly flirts with Spy Fox and dances with him during the tango.
- Genius Bonus: As mentioned under "Punny Name," the Greek island which Dry Cereal is set on is named Acidophilus, named for the bacteria which changes milk into yogurt. Bonus points for it's being spelled the same way in both Greek and it's original Latin.
- Hilarious in Hindsight:
- Most Wonderful Sound: A short background music appears whenever Spy Fox solved a puzzle.
- Nightmare Fuel: The Dummied Out death scene in Some Assembly Required. It's both very jarring incredibly dark for the setting, which is likely why it was cut. It's too bad, since it's a great Shout-Out to the Dragon's Lair games.
- Padding: The most common complaint with Hold The Mustard.
- Polished Port: The Wii Re-Release of Dry Cereal...
- Porting Disaster: ...which most people would criticize because of it's fast frame rate.
- Sidetracked By The Golden Saucer:
- Each of the minigames from the Spywatch, like "Happy Fun Sub" from "Dry Cereal", "Things From Space", a space shooter minigame in Some Assembly Required, and "Radioactive Trash Collector" Operation Ozone respectively
- The Go Fish game (whenever you get the Lucky Charm after being Big Pig or the Car Chase path) from the first game could also qualify.
- That One Level: Cheese Chase's Level 75, Carnival of Clouds. It's riddled with narrow pathways that are all one hit kills as well as plenty of cheese that leads to death traps.
- That One Sidequest: During the White Water path in Dry Cereal, one of the things mandatory is to beat Big Pig at Go Fish. He's very good at playing, so expect frustration to ensue. Other puzzles also require a strong understanding of math and telling time, two things younger players might not be as familiar with.
- They Changed It, Now It Sucks!: When Infogrames re-released the first game, the British dub somehow made it over to the States. For some, the new voice acting ruins it.
- They Wasted a Perfectly Good Character: Monkey Penny doesn't take a level in badass until the final cutscene of the final game, defeating the bad guy and even saving Spy Fox himself. The credits also reveal several potential Inspector Gadget-like cyborg parts in her paws and tail, enough for an entire other game's worth of Character Development.
- Values Resonance: While it was not unheard of in 2001, Operation: Ozone becomes a lot more relevant now that global warming and climate change have become more mainstream issues in the proceeding decades since it's release. It helps that it's Green Aesop is fairly subtle (it's mainly about how aerosol is harmful to the ozone), not to mention plot-relevant.
- What an Idiot!: In Operation: Ozone, late in the game, Pushpin gives Spy Fox the congeal pill that, when thrown into the pit of aerosol, will effectively destroy Poodles' entire space station and thwart her evil plan.
You'd Expect: For Spy Fox to throw the pill in quietly before saying a word.
Instead: He brags about it first, and then attempts to throw it in. Since he now has Poodles' attention, she's able to retrieve the congeal pill using one of her own gadgets and stop it from going down. She then traps Spy Fox in a steel net while she continues to finish up her evil plan.
You'd Then Expect: For Poodles to hang onto the pill herself, or better yet, destroy the thing so Spy Fox loses all of his chances at thwarting her.
Instead: She does nothing more but throw it into an empty trash can. In very easy reach of where Spy Fox was just standing. Apparently she had no forethought that he, a spy who was able to get past all her security and onto her spaceship, would maybe find his way out of this one.
Fortunately: He learns his lesson over that first point and keeps quiet when throwing it down a second time.
YMMV / SPY Fox
