This is a quiz segment that airs within NHK E Tele’s “Shakiin!” A band of mice tries to make its way forward while hiding in the shadows so as not to be spotted by a cat. The quiz is to count how many mice were in the band in total. With an emphasis on the interplay between the slightly dull-witted, fickle movements of the cat and the mice’s tense efforts to escape, each installment has been carefully devised to create variation.
