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 while waiting for the rain to clear up. 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.
