The Titans decide to help Cyborg conquer his fear of a monster that's summoned in darkness by hosting a sleepover.
- Absurd Phobia: Cyborg's fear of Scary Teri is played up as one of these, with the other Titans mocking him for it, and stating that real monsters like Raven's father wouldn't bother pranking young children unless he was really bored.
- Big Blackout: The Titans Tower, at least, is completely blacked out by a power shortage.
- Bigger on the Inside: Robin's blanket mansion is set up in the Titan Tower living room, but turns out to be the size of an actual mansion inside when they have to hide from Scary Teri.
- Blanket Fort: Or in Robin's case, an entire blanket mansion!
- By the Lights of Their Eyes: When the team comes to investigate Cyborg's room during the blackout, their eyes are like this, which make Cyborg think he's being attacked by a eight-eyed monster.
- The Cassandra: Nobody believes Cyborg regarding Scary Teri. When they force Cyborg to try summoning her to disprove her, she turns out to be real.
- Early-Bird Cameo: It's not until next season that we get an episode all about Cyborg's favorite song, "The Night Begins To Shine", but he's grooving to it at the start of this episode.
- Face Your Fears: Cyborg faces his fear of Scary Teri in the end, and successfully traps her.
- Here We Go Again!: Even after defeating Scary Teri, when the lights in Titan Tower go out again, he once again confuses the other Titans for an eight-eyed monster and starts shooting in panic.
- Laser-Guided Karma: The moment that Cyborg defeats Scary Teri and overcomes his fear by dispelling her with a hand mirror, the lights in Titan Tower come back on. Cyborg then slams the mirror on the ground in victory, breaking it, and the lights immediately black out again, causing Cyborg to panic.
- Overly Long Scream: Cyborg screams in his flashback when he sees Scary Teri. Cut to the present day and Cyborg is still screaming.
- Running Gag: "EIGHT-EYED MONSTER!"
- Shapeshifter Scary Teri initially appears to be a floating white-haired girl with an unkempt appearance before turning into a purple demon. While chasing the Titans in the blanket mansion, she also transforms into a door to trick Beast Boy, and a snake to chase Cyborg into a room.
- Shout-Out: To the Bloody Mary urban legend.
- Slumber Party: A coed example, in which the Titans have their slumber party together.
- Speak of the Devil: Saying "Scary Teri" in front of a mirror three times will summon her.
- The Stinger: Batman and Commissioner Gordon are still laughing at the TP'd statue at the end of the episode.
- Toilet Paper Prank: The Titans pull one on Batman, who finds it hilarious.
