Sakata makes a Goma-chan suit to make his brother happy, but before he can put his plans to action, Big Bro takes the suit to show it to Goma-chan.
As he walks the neighborhood wearing a Goma-chan suit, everyone thinks he’s the real Goma-chan. Meanwhile, Sakata finds the real Goma-chan but thinks he found his brother in the suit...
Goma-chan isn't going to 
stay a baby forever, sir.
لن يبقى غوما-تشان طفلاً للأبد يا سيّدي
Goma-chan bleibt doch
nicht für immer ein Baby.
Goma-chan no será siempre una bebé.
Goma-chan no será siempre una bebé.
Goma-chan non rimarrà
un cucciolo per sempre, signore.
A Goma-chan não vai ser um bebê para sempre.
