[Machine Translation] Based on Michio Mado's poem of the same title, this picture book humorously depicts a parent-child interaction with a gorilla. Parents and children can enjoy playing with the gorillas by touching them here and there in time to the rhythmical sounds of "head tentsen tentsen," "cheeks pom pom pom," and "feet tumen dong dong". At the end, please enjoy "Ashi-no-ura wo kocho kocho"! <p> ( Written and illustrated by Keiko Nabeta ) </p
