This article features notable quotes from Season 3, Episode 12A "Moth on the Moon".
- Luna Girl: "Help hatch it? I'm not sitting on it!"
- Luna Girl: "I'm pretty much set: Lunar Fortress for her to play in, pictures of her big sis to admire."
- Catboy: "Stealthily, Catboy explores the moon cave..." (Owlette's PJ Rover drives towards him, causing him to fall down)
- Owlette: "Catboy!"
- Catboy: "How can I be stealthy if you send the rovers racing around?"
- Luna Girl: "It's Motsuki. My moth who's turning into... a girl."
- Luna Girl: "Aww, we are going to have such fun together! Remember the PJs?"
- Motsuki: "They fight, they argue, they made me hatch!"
- Catboy: "You... you used us!"
- Motsuki: (Squeaks) "I can say bad things. Things that make people get angry!"
- Luna Girl: "Okay, little sis, let's take them to the Lunar Fortress, drain their powers."
- Motsuki: "Maybe."
- Luna Girl: "Maybe?"
- Luna Girl: "You can fly me through space? To the moon and back again? We might get along after all."
- Motsuki: (Flies inside the moon bubble) "Eep! Give me magnet!" (Aims and fires the weapon at the HQ Rocket)
- Luna Girl: "Wow! Your crystal, it's supercharging! Wee!"
- Owlette: "Too bad we accidentally helped hatch a brand new villain."
- Catboy: "We'll work out how to handle her. Get ready, Motsuki! You've got us to deal with."
