Kevin makes a fine Father Christmas and knows the ideal gift: a dog, but Lucy insists to wait till after the holidays, then sneakily goes to the asylum herself, only to find their tastes in canines differ greatly. Heathen Rose has no clue what Christmas has to do with Nativity, so she 'tests' the twins, but in the process makes them doubt if either Santa or Jezus really exist. Sandy isn't keen either to participate in the parish's nativity scene. In the end, things work out as by Christmas magic.
