The first cube was found by gosling and he decided that it should belong exclusively to him, because his head is drawn on one side. But the puppy categorically disagreed. Why this cube should be at the gosling, if on the other side the dog's ear is drawn. The goatling found two more cubes, and it did not even occur to him that the cubes belonged to him, because on both sides his parts were clearly drawn. The kitten was the most cunning. Finding the fourth cube, he took possession of three at once and tried to convince the company that this was done fairly. Kids almost quarreled, but eventually it turned out that there must be four cubes and they can not be broken. Only in this case it is possible to add them so that the portraits of each of the friends turn out. It's good, after all, when friendship, peace and harmony win.
