Thank you very much for viewing. Kodomo Challenge Ikimono Kansatsu Navi (Creature Observation Navigator) There are 29 cards. Card number 18 is missing. There may be some minor scratches, but I think they are in relatively good condition. When you insert a card and press the button, you can hear the sound of the creature's call. There is a quiz where you listen to the call and guess what creature it is (cicada, bird, insect, etc.). Even cicadas have different calls depending on the species, and you can learn about those differences, which is fun for parents and children. The sound of the Higurashi cicada is soothing! We hope you will consider this item, understanding its condition.
