It's fun! It's easy! They only cost a measly dollar. Just clip out the ad in your comic book. Then ask Mom to mail it in. A few weeks later, receive a packet of instant Sea Serpent dust. Then:
Just add water . . . and watch them grow!
WHAT COULD GO WRONG?
Just ask David and Patrick. Their "instant pets" are instant duds. They don't hatch, they don't grow, they don't do anything. So they dump them into the sewer where Dad pours toxic chemicals . . .
WAIT UNTIL FEEDING TIME.
It's been years since David and Patrick thought about those Sea Serpents. But now, small animals are disappearing in the neighborhood. Strange slimy creatures are rising from the sewers. And once the screaming starts, David and Patrick realize that their childhood pets really did come to life. With a vengeance. They're enormous . . . and have a ravenous hunger for human flesh . . .
