->''He who faces himself, finds himself.''
Several Jedi younglings are taken to the icy planet Ilum to face their greatest challenge yet: obtaining kyber crystals for themselves in order to build their own lightsabers. This has to be done before the doorway to the cave containing the crystals is frozen over, trapping them inside for several more rotations.
!! This episode provides examples of:
* AnAesop: Each youngling has to learn one in order to get their kyber crystal.
* BackdoorPilot: The whole Younglings story arc was conceived of as a pilot movie for a potential ''Younglings'' spinoff, but was folded back into the main ''Clone Wars'' show after George Lucas changed his mind after test screenings.
* HotBlooded: Gungi. He gets better.
* ItsAllAboutMe: Petro. Like the others, he gets better about it.
* LovableCoward: Byph. He gets better, though.
* SecretTestOfCharacter: What the children endure in the cave, as they are able to conquer their own weaknesses.
* SnowedIn: The children narrowly escape this fate at the end, though it turns out that it wouldn't have been a serious issue -- Petro is able to smash his way through the ice barrier just after it freezes.
