I'm particularly fond of 'Sleepytime', but 'Rain' is probably the episode that I've thought of more often than any other. Because of that 7 minute cartoon episode, I have found myself _actively_ changing my behavior/decisions with my kiddo - letting them do something that will be a bit more work for me later on (extra laundry or whatever), but something that sparks their curiosity or gives them a new experience or similar.
