Several Jedi younglings have 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:

* HotBlooded: Gungi. He gets better.
* ItsAllAboutMe: Petro. Like the latter, he gets better about it.
* LovableCoward: Byph. He gets better, though.
* SecretTestOfCharacter: What the children endured in the cave was this, as they were 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.
