A baby has come to visit Ashibe-kun's house! It's Yumiko-chan's baby sister, Ruriko-chan! Ashibe-kun and his Ma and Pa are all so enamored with Ruriko-chan that Goma-chan isn't getting any attention, making him a bit grumpy. Ruriko-chan appears to like Goma-chan, but Goma-chan is irritate that she treats him like a plaything. And so the battle between Goma-chan and Ruriko-chan begins?!
When Ruriko-chan is crying, 
it makes us want to cry, too.
عندما تبكي روريكو-تشان فإنّها تحثّنا
على البكاءِ أيضاً
Wenn Ruriko-chan weint,
kommen uns auch die Tränen.
À force de l’entendre,
j’ai envie de pleurer, moi aussi…
Se Ruriko-chan piange, 
viene da farlo anche a noi.
Se a Ruriko-chan chora, até
eu sinto vontade de chorar.
Когда Рурико плачет,
нам тоже хочется плакать.
