Tropes:
- 90% of Your Brain: Richard believes the box is a phone, and answering it will reveal himself to be a Manchurian Agent made hypercompetent by unlocking all of his brainpower. His Imagine Spot continues with Richard saving the president from being kidnapped (and starts to make out with him). Gumball insists, because "100% of nothing is still nothing", Richard would be an idiot anyway, causing an altered version of the Imagine Spot where Richard is as stupid as usual and fails miserably.
- Briefcase Full of Money: Nicole thinks the box might be full of money. She further posits that it's owned by a criminal, who'll send a series of hitmen after the Wattersons, forcing them to live on the run for the rest of their lives. She's fine with that though, as long as they're still rich.
- Bring My Brown Pants: Implied in Nicole's fantasy when the family is running from a hitman.Anais: I think I know how he's tracking us!
Richard: I'm sorry! I'm just so scared!
Anais: What the?! Not that. - Body Horror: Gumball's mutations from the teleportation gun; it starts with his nose mutating into a highly detailed face, then the doctor predicts continued use will mutate him into a cyst-like mass of flesh covered in tongues where they shouldn't be. Concluding there is a very small chance to develop superpowers he tries going through with a bird, chameleon and a frog to develop their respective abilities. This just leaves him bloated and misshapen with three arms, a chameleon tail and laying eggs of all three species out the side of his head. At Darwin's suggestion to try and improve his appearance he tries merging with something cool looking, which he concludes to be a cockroach.
- Fantasy Twist:
- Gumball's teleportation gun idea ends with him becoming hideously mutated.
- Nicole's money idea has her and her family forced to live on the run from criminals for the rest of their lives.
- Forbidden Fruit: Anais discourages opening the box as it's a felony, which makes Gumball want to open it more. Richard likens it to being told not to stare at the sun, and then Nicole has to tell him he's facing the wrong way.
- Freudian Slippery Slope: Nicole tries to suggest distractions so they won't be tempted to open the box but she keeps ticcing and suggesting box-related activities until she's raving they hurry up and open it.
- Imagine Spot: Each of the Wattersons' curiosity on what is inside the box.
- Insane Troll Logic:
- Gumball argues that he could eat for free if he lived in a supermarket, arguing that it's technically not stealing if the food enters and exits your body while you're still in the store.
- Gumball presumes the box contains a teleportation gun based on shaking it. Anais points out he couldn't possibly know what a fictional object sounds like, but he rebuts the family can imitate the sound of a Laser Blade.
- It Came from the Fridge: Warning against opening the box for fear of it being Sealed Evil in a Can, Anais compares it to Pandora's Box, the Ark of the Covenant and the spoiled takeout box at the back of the fridge. It's depicted as an arm of noodles about to assault a shocked Richard.
- Kids Prefer Boxes: Darwin wonders if the box is empty, and thinks of all the things they could pretend it is. Gumball says that would just be a huge letdown, even grabbing the screen to cut off Darwin's attempt to sing about it.
- No, You Hang Up First: Richard while on the phone in Gumball's version of his fantasy, despite the phone about to explode and the speaker being a recorded message.
- Only Sane Woman: Anais is the only one of the Wattersons to be against opening the box, for two reasons:
- 1.) It's technically a felony to open up someone else's mail.
- 2.) The box's contents could be something really dangerous—because of that, Anais argues that maybe the box was never meant to be opened.
- The Reveal: In the end, we find out the contents of the box were cream for an insanely bad skin rash.
- Shout-Out:
- Gumball thinks the box contains a portal gun modeled after the one from Portal. His Imagine Spot eventually segues into the plot elements of The Fly (1986).
- Nicole's scenario is an abridged Whole-Plot Reference to No Country for Old Men.
- Among the examples of Sealed Evil in a Can mentioned by Anais are the Ark of the Covenant.
- Skewed Priorities:
- Gumball is extremely desperate for superpowers and so is willing to risk his health using the mutagenic teleportation gun trying to get them in spite of the doctor impressing how utterly implausible this is.
- Nicole is willing to put the family on the run, hunted for the rest of their lives as long as they're millionaires.
- Teleportation: Gumball thinks the box is a portal gun. After using it for many mundane tasks, it turns out to cause terrible mutations, made worse by Gumball repeatedly teleport merging himself with numerous animals in an attempt to get superpowers.
- This Page Will Self-Destruct: The phone in Richard's fantasy, which he uses to dispatch the villain. In Gumball's version, Richard keeps talking on the phone until it explodes on his face.
- Too Much Information: Mr. Robinson gives a very long, very detailed description of the kind of rash he has that he bought cream for.
- You Do NOT Want To Know: The box turns out to be for Mr. Robinson, who says the Wattersons don't want to know what's inside, but they insist after wondering the entire episode. He then goes into a very graphic, very long description of a repulsive skin condition the box contained an ointment for. They agree they didn't want to know.
- Zombie Apocalypse: Anais thinks the box could be full of Mutagenic Goo that Richard will play with, making the family Patient Zero in a zombie apocalypse that turns the planet itself into a zombie.
