Something is amiss at Toad Island. Fish-like people are kidnapping patrons to appease something called the Deepest One. However, one of the Toad Islanders fights the calling of his people and goes to the Ghostbusters to help stop the evil at the amusement park. Unfortunately during the course of their investigation, Janine is kidnapped by the fish people, giving the Ghostbusters one more person to save!
Janine’s hairstyle changes from the style common to the early seasons of Real Ghostbusters to the style that began in the episode "Baby Spookums" and carried on for most of the later seasons and Slimer! & The Real Ghostbusters, then goes back to the other style by the issue's end.
