The Christmas season proves to quite an exciting time for Fat Albert and his gang when Marshall`s mom turns up at the junkyard looking for a place to deliver her baby. Busy preparing for the Christmas pageant, the Cosby Kids take a break in order to help Marshall`s folks, who cannot go to the hospital because they have no health insurance. As they open up their doors to this family in need, the kids hope that somehow their generosity and holiday spirit will rub off on Tyrone, the stingy junkyard owner who`s been threatening to close their beloved clubhouse down.
