Since becoming friends with Dot-chan the whale shark, Goma-chan doesn't seem to understand anything Ashibe-kun says anymore. With Goma-chan staying at the aquarium, Ashibe-kun is alone and sad at home... but then Sugao-kun brings him a stack of books on seal language. Time to try one more time to communicate with Goma-chan using seal language! Will Ashibe-kun's feelings finally reach him?
I know not only seal language, 
but whale and jellyfish languages, too!
لا أعرف لغة الفقمة فحسب، بل لغة
الحوت ولغة قنديل البحر أيضاً
Ich spreche nicht nur fließend Robbensprache,
sondern auch Wal- und Quallensprache.
Domino el lenguaje de las focas, 
las ballenas y las medusas.
Domino el lenguaje de las focas,

Je parle le phoque couramment,
mais aussi le baleine et le méduse !
Não é só a língua das focas, também sou
fluente na língua das baleias e águas-vivas!
Помимо тюленьего, я также 
знаю язык китов и медуз.
