Ashibe-kun wanted to gather chestnuts, so his grandpa bought a mountain for him! Goma-chan has never had chestnuts before, so he's excited, too! Now, let's all go pick up chestnuts together! The gang searches the ground in a grove of chestnut trees, but... what? There are no chestnuts anywhere. Then they find some mysterious footprints... Could the one who ate all the chestnuts be the unidentified creature Cheskenstein?!
buying one little mountain is nothing.
فإنّ شراء جمبل صغير أمر بسيط
ist doch nichts dabei,
so einen kleinen Berg zu kaufen.
y no me costaba nada 
comprar una montaña.
y no me costaba nada
comprar una montaña.
pour que son petit-fils
puisse y cueillir des châtaignes.
comprare una piccola montagna è una cosa da niente.
sai barato comprar uma montanha.
то я не пожалею пары йен
 на покупку горы.
