Craig, Kelsey, and J.P. find themselves on an island with kids who can't stop tattling.
Tropes:
- All for Nothing: The "Mind Your Business" lesson doesn't stick as the tattlers go back to their old ways when they catch Lucius making a mess.
- Bitch in Sheep's Clothing: Lucius offers to repair the Stump Trio's raft on the condition that they take care of his students. In truth, he only wanted them distracted so he can steal their raft and sail away.
- Continuity Nod: Craig's lesson on "Mind Your Business" was inspired by his Uncle Darnell which would explain how his cool cousin Jasmine adopted the line as her Catchphrase.
- Does This Remind You of Anything?: Lucius and briefly the Stump Kids attempt to convert some kids on an island. This is clearly allegorical to missionaries.
- Freak Out: Lucius, already disillusioned with ever teaching the tattlers to stop tattling, loses it when he threatens to tattle on the Stump Kids and starts acting hysterical at realizing he's become a tattletale as well.
- A Lesson Learned Too Well: The Stump Trio succeed in getting the tattlers to stop. Unfortunately, now they won't warn them about Lucius taking their raft.
- Out-of-Character Moment: J.P., usually the most mild-mannered of the Stump Kids, is the one who yells at the tattlers to sit down and shut up.
- Sanity Slippage: Trying in vain to reform the tattlers has made Lucius go crazy.
- Saying Too Much: J.P.'s lesson on tattling results in him telling a time Craig had diarrhea and clogged his toilet which forced J.P. to throw him under the bus when Nicole asked who was responsible.
- Screw This, I'm Outta Here: Lucius has long failed to teach the kids not to tattle, and tricks the Stump Kids into trying while he fixes their raft to steal.
- Shout-Out: The "Mind Your Business" song visually recalls Schoolhouse Rock!.
- Sure, Let's Go with That: J.P. and Kelsey try to justify them leaving Lucius behind saying that they did their best.
