"Hello! This is Koiwai Yotsuba, Yotsuba Koiwai ... um, YOTSUBA! Yotsuba moved with Daddy to a new house from our old house waaaaaaay over there! And moving's fun 'cos people wave! (Ohhhh!!) And Yotsuba met these nice people next door and made friends to play with (one of 'em acted like one of those bad strangers Daddy told Yotsuba not to go with, but it was okay in the end). I hope we get to play a lot. And eat ice cream! And-and-and ... oh yeah!...

Yotsuba meets a Robot at Ena's house and would like to know more about its behaviors.

Yotsuba is trying her hand at drawing, but a few ruthless art critics could squash her dreams. A new love for gangster movies will tear her away from her artistic endeavors, when this green-haired girl-turned-goodfella uses her trigger-happy tactics to douse her doubtful neighbors. But when Yotsuba's water pistol runs out of ammo, our hugable thug learns that revenge is a dish best served dry.

Yotsuba loves playing games and she is good at it. Daddy's opinion is that Yotsuba makes the rules as they play along, but she thinks that he is a sore loser. But maybe Yotsuba will let him win once in a while.
