“Deep Down in Darkness!” Guest-starring Spider-Man and Kitty Pryde. Script by Bill Mantlo. Pencils by Ron Frenz. Inks by Mike Esposito. Cover by Ron Frenz and Al Milgrom.

The story starts with a bang as Spider-Man desperately tries to stop a runaway subway train! Heroically, the web-slinger prevents a major catastrophe, but falls unconscious doing so…and then falls into the hands of the Morlocks! Meanwhile, Kitty’s adventure into babysitting goes awry when the two children she is supervising jump into a deep backyard pit. And that seemingly bottomless pit leads all the way…to the land of the Morlocks!
