Sakata's big brother's love for Goma-chan can't be stopped. It's reached a point where everyone is starting to worry about Goma-chan. So Ashibe-kun and his friends decide to try to help Sakata's big brother "graduate" from Goma-chan! They attempt several things, like trying to get him interested in other animals and popular idols... but can Sakata's brother ever outgrow his love for Goma-chan?
It's not like the real 
Goma-chan talked, you know...
تتكلّم وكأنّ غوما-تشان الحقيقي قد نطق
Es hat aber auch nicht
der echte Goma-chan gesprochen …
En realidad no fue Goma-chan
el que habló.
Ce n’est pas Goma
qui a parlé, tu sais.
Guarda che non è stato
il vero Goma-chan a parlare...
Mas a Goma-chan não
falou de verdade, sabe...
Вообще-то с братом Сакаты 
разговаривал ненастоящий Гома...
