Classic Castle
“One great example is set 1078, released in 1987. Kids can build the 72 patterned 2x2 tiles on 4 red 6x12 Duplo plates to create horses, goats, ducks and, of course, cows. Related sets 1014, 1019 and 1079 have kids building a variety of other animals including household pets... More and wild jungle animals.”
