Summary[]
Goodie the Gremlin is reading a book by a fireplace while Meany and an unnamed gremlin are playing checkers. Meanwhile, young Impy is playing with a train set. When he creates a collision on the tracks, he erupts in pure joy, much to Meany's irritation. Before Impy goes to bed, Goodie decides to tell him a few stories about his exploits -- which naturally involve sabotaging the plots of his fellow gremlins.
