Lying Around the House: The girls' (and Professors') little white lies turn into a big problem when a monster starts to grow and make trouble around the house.
Bubble Boy: Bubbles goes undercover with the Rowdyruff Boys by pretending to be Boomer (who has been ambushed by the girls). Unfortunately, she is not exactly cut out to be Rowdyruff material.
Lying Around the House provides examples of:
- An Aesop: Lying is bad no matter how big or small they are.
- Blatant Lies: The girls’ lies become this more and more as the episode continues, like Buttercup denying that she drank the chocolate milk despite some of it being on her upper lip, and Bubbles denying having touched the Professor's mutation chemical, despite having a squid arm now.
- Cordon Bleugh Chef: The Professor becomes one in this episode; the breakfast he makes for the girls is…Liver and Onions!
- Emotion Eater: A variation; the monster feeds on lies. The more lies told in its vicinity, the stronger it gets.
- Hypocritical Humor: The Professor talks about how he didn’t want the liver and onions he made for the girls to go to waste…while he’s throwing away the uneaten pancakes he made for himself.
- Informed Attribute: Both Buttercup and the Professor have left the toilet seat up. Buttercup leaving the toilet seat up may be a joke on Buttercup's tomboyish attitude, assuming she pees like a boy. (Of course, she could've noticed that the seat was up because of The Professor, and didn't fix it.)
- Kryptonite Factor: Confessing the lies it fed on and telling the truth instead weakens the monster.
- Oh, Crap!: Bubbles when she realizes she got so caught up in her drawing that she accidently drew on the wall. And Buttercup when she accidently destroys the professors award.
- Stuff Blowing Up: Blossom manages to blow up the washing machine by overloading it again.
- Title Drop: Done by the narrator.
Bubble Boy provides examples of:
- Achievement In Ignorance: The containment ray used to hold Boomer is yet another accidental invention of Professor Utonium.
- Bound and Gagged: The Rowdyruff Boys do this to Fuzzy Lumpkins when they break into his house.
- Containment Field: Professor Utonium invented one of these. It is powerful enough to hold all three Rowdyruff Boys.
- Dressing as the Enemy: Bubbles disguises herself as Boomer.
- Even Evil Has Standards: Even Brick and Butch are grossed out that Bubbles actually ate the cockroach.
- Evil vs. Evil: off screen, the Rowdyruff Boys vs Fuzzy Lumpkins. Fuzzy loses.
- Hidden Wire: Bubbles wears one so her sisters and the professor can follow what is going on.
- Hypocrite : Brick criticizes Boomer for saying “beating up people for fun is really fun”, even though Brick himself said it first. When called out on this, Brick simply handwaves it away with the statement that it’s only cool if he says it.
- If You're So Evil, Eat This Kitten!: When growing more and more suspicious about their brothers’ behavior, Butch and Brick demand that Bubbles eats a cockroach to prove she really is Boomer. She actually does (and claims later it Tastes Like Chicken).
- Lured into a Trap: Bubbles eventually lures Brick and Boomer to the Utonium house so they too can be captured.
- Mugged for Disguise: What the girls do to Boomer after capturing him.
- Nice Job Breaking It, Hero: Bubbles accidently frees the Rowdyruff Boys again when she tries to demonstrate her new spitting abilities.
- Super Spit: Butch and Brick both try to take out an airplane with their spit, but end up hitting a mirror that two astronauts were about to put into a satellite instead. When it’s Bubbles/Boomer’s turn, her spit, after ricocheting all over Townsville, ends up hitting Butch (which Brick considers even better than hitting a plane).
- Trying Not to Cry: Bubbles after being punched in the face by Brick.
