I like NISSHIN's TV CMs.
In this CM, it sings as "IKA KANA? (Is it squid?), IKA JA NAI (It's not squid)" repeatedly. And at last, it sings "IKA JA NAI KEDO, HOBO HOBO IKA YO(It's not squid but almost squid). DON'NA seafood? (What kind of sea food is it?)".
The girl is "HAYAMI, YUU" formerly famous bilingual "idle" singer who eats the seafood noodle.
