Noticing how vulnerable humans are to cute things, Zim attempts to weaponize the skool's pet hamster by turning it into a kaiju.
Tropes
- Adults Are Useless: The military never actually has much of a chance to do much against Peepi.
- The Comically Serious: Ms. Bitters introducing Peepi. That is all.
- Cuteness Proximity: Everybody who sees Peepi completely melts into baby-talking mush from his cuteness. Zim plans to weaponize this weakness by turning Peepi into a giant monster whom he can control, and while he fails to get the kaiju-sized Pipi to obey him, many citizens can't get away in time to avoid harm just because how taken they are with his cute antics.
- Cyborg: The hamster, upon getting larger, gains a robotic limb or two.
- Didn't Think This Through: Zim hits upon the idea of luring Peepi to a Ferris Wheel, rationalizing that the hamster will play with it like he did his normal wheel. Problem is, Peepi so huge now that said Ferris Wheel is little more than a collar to him, now.
- Dynamic Entry: Peepi is introduced to the class by way of a mechanical box that opens by launching its two halves into the walls, leaving the hamster cage revealed.
- Enemy Mine: Zim and Dib teaming up to stop Peepi's rampage.
- Extreme Omnivore: After Zim's experiments, Peepi eats anything. Chain-link fences, hot dog stands, nuclear power plants...it's all on the menu to him!
- Faux Horrific: Peepi approaches the side of his cage where Zim is watching, causing him to freak out.
- For Your Own Good: Zim takes this approach while fighting Peepi with his spacecraft.
- Funny Background Event: As Zim gives a half-hearted monologue about how the departed, launched-into-space Peepi will live on among the stars, we can see a streak in the distance - presumably, Peepi crashing back to Earth.
- Gone Horribly Right: Zim wanted to create a super-weapon so cute, everyone would be overwhelmed by its darling nature and thus drop their guards. Good news: Zim succeeded. Bad news: Zim couldn't control said monster.
- Kaiju: Peepi resembles Godzilla as he grows larger.
- Make My Monster Grow: The more Peepi eats, the bigger he gets.
- Mike Nelson, Destroyer of Worlds: The hamster's not actually malicious - it's just doing what hamsters would normally do. Problem is, it's so big that what it would usually do wrecks the city.
- Mundane Made Awesome: "THE WEENIE TEMPTS YOU!"
- No Animals Were Harmed: The episode ends with a disclaimer saying "No animated characters were harmed in the filming of this production."
- Ridiculously Cute Critter: Peepi's antics are absolutely adorable. Getting monster-sized doesn't subtract from this as much as you'd think.
- Sadistic Choice: Dib finds himself confronted with this when trying to decide whether to help an unconscious Zim, knowing he'll go back to trying to conquer Earth afterwards; or to turn him in to the authorities, leaving no one to stop Peepi. Also Subverted; while Dib is agonizing over the decision, Zim recovers on his own and escapes.
- Skewed Priorities: Everyone who sees Peepi doing hamster things while at monster size. One would think they'd be more concerned with running for their lives.
- Twinkle in the Sky: Peepi's ultimate fate, courtesy of some alien-tech rockets that Zim attaches to him.
- Uncertain Doom: Everyone who gets caught up in the hamster's rampage while being blinded by its cuteness. They're later seen posing with it in the No Animals Were Harmed disclaimer picture.
- Unusually Uninteresting Sight: Dib's the only one who thinks anything of the fact that Peepi's twice his original size and now sporting alien cybernetics after Zim gets at him. When Pipi starts getting bigger, well...then they notice.
- Villains Out Shopping: When it becomes clear Peepi is quite destructive and unstoppable on his own without Zim's control, the alien decides to just casually watch TV at home with GIR.
