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?!
My lullaby is better!
!تهوديتي أفضل
Mein Schlaflied ist besser!
Mi canción de cuna es lo mejor.
¡Mi nana es mucho mejor!
Laisse-moi chanter ma berceuse !
La mia ninna nanna è meglio!
A minha canção de ninar é melhor!
Моя колыбельная лучше!
