Granny doesn't want Noelle to marry an "impure human" so she goes off in a huff when the family starts discussing marriage plans (ignoring Yuusuke's objections). Miruru and Granny team up to try and get Yuusuke out of the picture (Miruru telling Granny that she loves Yuusuke and wants him for herself). So the newest robot has a ukulele that can turn people into frogs. Slowly each family member is turned into a cute little frog until Yuusuke is the only one left (Miruru betrayed Granny so even she is a frog) and has to figure out how to save everyone. He thinks you have to look into the ukulele's eyes but it's the strings that hold the magic.
La abuela no quiere que Noelle se case con un "humano impuro", por lo que se enfada cuando la familia comienza a hablar sobre los planes de matrimonio (ignorando las objeciones de Yuusuke). Miruru y Granny se unen para tratar de sacar a Yuusuke de la escena (Miruru le dice a la abuela que ama a Yuusuke y lo quiere para ella). Así que el robot más nuevo tiene un ukelele que puede convertir a las personas en ranas.
