You have to say things that connect to each other via the last syllable of the prior word.

It has to be first a food, then a celebrity, and then an animal

It has to begin with whatever the narrator says and that girl had "mu" as her starting syllable and she had difficulty with a food.

First she said "mushi"--which is an insect, and then she said "mushi soba" so she has to start the celebrities name with a "ba" or "ha" sound and she picked "Hamasaki Ayumi" and then the animal was "mimizuku" which is a type of owl.

So it went Mu -> Mushi soba -> Hamasaki Ayumi -> Mimizuku

But they didn't accept mushi soba as a food so she begged to have a second chance, which they gave her. But she failed her second time too, which she had to do with "se" starting her off.

Apparently "mushi soba" wasn't "general" or popular enough lol.
