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?!
Yumiko-chan, your mommy 
told me you'd be here.
يوميكو-تشان، قالت لي أمّكِ
أنكِ ستأتين إلى هنا
Yumiko-chan, deine Mama hat
mir gesagt, dass du kommen würdest.
Tu mamá me lo contó. 
Siéntete como en casa.
Ya me lo dijo tu madre.
Siéntete como en tu casa.
J’ai eu ta maman au téléphone,
Yumiko.
Yumiko-chan, tua madre
mi ha detto che saresti venuta.
A sua mamãe já me avisou, Yumiko-chan.
Твоя мама сказала мне, что задержится.
