Spanky wants to go play football with the other kids. However, his mother is irresponsible and tells him he has to stay home and take care of his baby sister. I guess in the mid-1930s this seemed like a good idea, but this is a very YOUNG Spanky and leaving him with a toddler is insane. Nonetheless, Spanky figures if he can get the baby to sleep, he can then sneak out to play ball. But the mischievous baby isn't sleepy and she'd much rather get into trouble! And, each time they DO get her to sleep, something invariably happens to stop them from leaving the kid. All in all, a simple idea that worked well. A decent short and an improvement over their previous outing.
By the way, the baby is quite adorable--and seeing this cutie jumping in mud puddles is reason enough to watch this short.
