Robin heads to the Batcave on what he claims is an important mission and can't take the team with him. So naturally they follow behind.
Tropes in the episode include
- Frame-Up/Kilroy Was Here: Robin leaves "The Joker was here" graffiti on the ruined Batmobile to pin the blame on the Clown Prince of Crime.
- Jerkass: The other Titans when in the Batcave. Starfire and Raven do not do any damage, but Cyborg and Beast Boy destroy the T-Rex, break open the glass case containing Batman's most prized possession, and then proceed to use it like a toy.
- Jerkass Has a Point: Robin didn't want the Titans coming with him to the Batcave because he was afraid they'd wreck the place. They then immediately prove him right by destroying the dinosaur, putting on other costumes, and breaking open the case holding the ultimate batarang...which they then use like a frisbee.
