Monster Exchange student Lorna McNessie can’t resist a scary-fun photobomb op--at home in Rotland or at Monster High.
It's the end of the scaremester at Monster High, which means that the new school fearbook has been published. Frankie, Clawdeen, Cleo and Spectra go to pick up their fearbooks, and Frankie decides to take a picture of her friends. She's surprised to see a water creature suddenly appear in the picture behind her friends. The water creature pops up behind them and introduces herself as Lorna McNessie, a new Exchange student visiting from Rotland. She mentions that her father is the Loch Ness Monster, and tells the tale of how she came to Monster High...
Below the waters of Loch Ness, Lorna swims toward her castle home, taking a moment to surprise the guards at the gate. She meets her father inside, and asks him if she can go above the surface. He forbids her, explaining that the last time he went up his photo was taken, and since then, normies have constantly visited the lake searching for him. Lorna lays on the charm and her father relents, allowing her to go up for one hour.
Lorna swims up to the surface, and has fun catching a ride on a speedboat, and watching some humans play golf. She then sees a photographer about to take a picture of the loch, and is overcome with the urge to photobomb it. She jumps into the frame and surprises the photographer, resulting in a blurry picture of her. The picture hits the news, and soon hundreds of people are exploring the loch, even diving underwater. Lorna's father is not pleased by this. He decides they need to get away until the commotion dies down, and arranges for Lorna to visit Monster High on the Exchange program.
Lorna finishes her story, and Frankie welcomes her and wishes her luck on her first day. Lorna replies that it's not her first day - she's been here all scaremester. The ghouls look through their fearbooks, and discover Lorna has photobombed every picture inside it.
- When Clawdeen flips the pages of the fearbook to check for Lorna, the photos Lorna has photobombed are callbacks to "We Are Monster High", "Zombie Shake", "Jungle Boo-gie", "Join the Scream", "Just One of the Ghouls", and "So You Think You Can Date", all occurances that happened further in the series.
- Lorna McNessie and the Loch Ness Monster make their cartoon debuts.
