♦ You'll want to meet your beloved grandparents!
Popo-kun and Tama-chan's grandpa hippo is great at running, swimming, and eating! He's a grandpa they're proud of. One day, Popo-kun drops his fishing rod into the pond...
A humorous story by the popular picture book author duo, Kenta Otsuka and Yuka Kitamura, who have many successful works. The unexpected ending will surprise you and make you laugh! It's a picture book that will make you want to chat and play with your beloved grandparents.
♦ From author Kenta Otsuka
The episodes and experiences shared by grandfathers and grandmothers sometimes surprise us. When their stories are too wild, we might feel like doubting them, thinking, 'Is that really true... isn't it a lie...?' But then, since grandfathers and grandmothers are telling them seriously, we might feel like we have no choice but to believe them, thinking, 'Maybe it's true after all.'
Popo-kun and Tama-chan, the grandchildren, seemed to listen to Grandpa Hippo's unbelievable episodes, like playing with dinosaurs or traveling around the world with whales, with a strange feeling, thinking, 'Is it true? But...' Perhaps Grandpa Hippo just wanted to see his grandchildren's surprised faces and excited expressions. Which is it, in reality...?
In any case, I think grandfathers and grandmothers in the world are truly powerful and energetic. Moreover, they have experienced so many things in their long lives, so there's no competing with them. I also want to become a wonderful grandfather who can say, 'Now is my prime,' no matter how old I get.
