Elfquest/Nightmare Fuel


 * One side-issue of Elf Quest starts with a Muggle couple fleeing into a forest of cute six-inch-tall butterfly-like critters who like to cocoon up sleeping animals, "preserving" them exactly as they are. The Preservers have forgotten why they do it, and so never get around to undoing it. They're adorable. They're friendly. They have cutesy names for everything. The couple meets them instead of the 'evil spirits' they were expecting, chats with them for a while, and eventually the Preservers chase off the couple's pursuers. The grateful duo can't wait to go set the record straight about the "evil spirits," who were definitely not to be feared. They fall asleep, watched over by their new friends.  The end!
 * However, in Elf Quest #10: The Forbidden Grove Cutter and Skywise discover the Preservers in the aforementioned forest and among other things, cut the couple (their nudity now slightly more censored) out of the cocoon and let them go. The narration implies that they've been in the cocoon for a year, sleeping peacefully, safe and sound, and none the worse for wear. So... Nightmare Retardant?
