Willa has several books from a series about a Little Blue Truck, it’s friends and helping those friends.   Grandpa made her a Little Blue Truck wooden toy for Christmas. Prior to opening her gift she constructed a tow truck from tinker toys to help her Yellow “Wheelie” School Bus, also from Grandpa, navigate the “mud” (carpet) in her bedroom.  The new toy became an instant success by pushing the bus out of the “mud”. Makes Grandpa really proud.
