Cyborg and Starfire, after spending all night immaturely pranking Robin and then accidentally left behind when the other Titans leave in the morning, decide to prove their maturity by defending Titan Tower from invaders.
- Booby Trap: As the episode title indicates, Cyborg and Starfire set these up when they're left behind in Titan Tower. When the other Titans return for them, they end up being the trap's victims, subjected to things like swinging logs, an electrified kiddy pool, and a live grenade activated by opening a door.
- Dramatic Irony: The first trap that the other Titans set off when they return for Cyborg and Starfire completely covers them in bee stings and honey, leading Starfire and Cyborg to believe they're dealing with a monster invasion and that they've successfully proven their maturity by dealing with them when in fact they've just tortured their friends.
- Indy Escape: One of the Booby Traps that Cyborg and Starfire set up is a huge rolling boulder, which forces the other Titans to run straight into a pit that ejects them from the Tower.
- Whole-Plot Reference: To Home Alone, with Cyborg and Starfire being forgotten when the other Titans go on a road trip and deciding to prove their maturity by defending Titan Tower from any intruders.
