Official Hdbk. 399, Hat Ball, Baby in the Hat, or Roley Poley. . . A soft ball and a supply of marbles, pebbles, or small sticks are provided. These latter are called “babies.” One scout is chosen “it”; the others line up each behind his own hat. “It” throws the ball at the hats. Each time he throws and misses, a “baby” is placed in his hat. When the ball lands in a hat, the owner of the hat takes the ball, while all the other scouts run away. As quickly as possible he throws the ball at one of them. If it hits the scout, a “baby” is placed in that scout’s hat and he becomes “it” for the next game. If he misses, a “baby” is placed in his own hat and he becomes “it” for the next game. . . Where hats are not available, small holes are dug in the ground and the ball is rolled into them. The game then continues as above. This version is called Roley Poley. 1957 Sat. Eve. Post Letters cnNY (as of c1900), You do not mention one of the best [games] i.e. “Baby in the Hat”!
