More about Eddie, this time in connection with a newcomer, Sidney Stewart, or Kidney Stew- as you wish- who turns out to be a girl rather than a boy. Anxious to get acquainted with his new neighbor, Eddie runs over to help ""him"" unpack on moving in day, finds out about his animal collection and how a recent, still bandaged head injury necessitated a crew cut. Then, when his mother springs the news that Sidney is a girl, is Eddie ever mad! But as anger cools, one thing leads to another and pretty soon everyone's having more enterprising times together.
