Lilo, Mertle, Stitch, Jumba, and Pleakley go out on a hiking adventure to try to prove the existence of the Night Marchers (an ancient Hawaiian legend), and later tell each other frightening stories. Meanwhile, an experiment that produces a loud, high-pitched shriek is being pursued by Gantu.
- Moral: You don't always have to prove you're right; it's often better to simply trust your instincts.
- Jumba's scary story is a parody of Victor Frankenstein and his monster, while Pleakley's scary story is a parody of both The Blob and its 1988 remake.
- Belle is one of two known experiments that lives with Lilo and Stitch, the other being Glitch.
