Lula's older sister, Molly, is coming to visit Udrogoth—and as it turns out, Lula had made some stuff up about the rest of the family in order to impress her sister, who's always looked down on Lula.
Molly eventually discovers the truth while Lula also discovers the real reason why her sister came to visit.
This episode contains examples of:
- Big Sister Bully: Molly was this to Lula when they were growing up—and she still kind of is until she and Lula manage to patch things up.
- Exact Words: After Lula claims that she doesn't have any other sisters outside of Molly, Poseidon's Trident shows up at the front door of the castle—Lula then claims to Dave and the others that Poseidon's Trident is her cousin and not another sister.
- Given Name Reveal: Near the end of the episode, it's revealed that "Molly" is actually short for "Mjölnir" (i.e., the hammer used by the Norse God, Thor).
- Mutual Envy: Lula was always envious of Molly when they were growing up, but after revealing the truth to her sister, Molly (instead of mocking Lula) admits that she feels Lula actually has it really good (better than she herself does). Also, after Lula gets Thor and Molly to talk things out, Molly confesses that, when they were growing up, she was secretly envious of Lula (mainly because of Lula's status as "the smart one" of the two sisters).
- We Are Not Going Through That Again: At the end of the episode, Poseidon's Trident (Molly and Lula's cousin) comes by and reveals that she broke up with Poseidon—Dave and the others respond to this by slamming the front doors of the castle shut again, clearly not wanting what would probably just be a repeat of what happened between Molly and Thor.
