The world of Aleen is torn by a planet-wide seismic disaster. Padmé dispatches Commander Wolffe and his clone troopers to help evacuate the survivors and rebuild their settlements, then join Plo Koon's forces as was their original mission. R2-D2 is on board to interface with and repair the Aleen central computer, with C-3PO along to serve as a translator.
- Breather Episode: Compared to the otherwise serious stories in the series' fourth season, this episode and the next one are lighthearted romps.
- Bulungi: Aleen, home to a tropical tribal culture of small humanoids, has shades of this.
- Deadly Gas: The planet's air is toxic to the lifeforms below the surface, as is the underground air to the Aleena, and the seal that prevents them from seeping past each other must be replaced properly.
- Down the Rabbit Hole: How R2-D2 and C-3PO get into their adventure.
- Glad I Thought of It: R2 realizes that "water" is the solution to Orphne's riddle, but 3PO quickly assumes that he thought of it, and continues to press the idea for the rest of this episode.
- Going to Be One of Those Days: Clone pilot Warthog, upon seeing the diminutive lizard-like natives:"Oh, great, this is going to be another one of those planets."
- Grumpy Bear: Commander Wolffe is uptight and strict, in contrast to the episode's more relaxed atmosphere.
- Plant Person: The creatures of Aleen's underworld are Ent-like humanoids who are initially hostile to intruders.
- Riddle Me This: How Orphne gives the droids clues for the way back to the surface.
- Ridiculously Cute Critter: The Aleeni are designed to be totes adorbs and fun.
- Robosexual: Orphne, the underground fairy, acts like she's attracted to C-3PO.
- Shout-Out: C-3PO's fearful reaction to the lights of the tunnel and R2-D2 extinguishing them with spray only for them to manifest again resembles Gimli frantically trying to fight off the spirits in the Paths of the Dead.
- Will-o'-the-Wisp: Orphne first manifests in the form of light circling the droids and then leading them down the tunnel.
