熱川バナナワニ園 have many greenhouses accommodating tropical fruits, flowers and the manatee boy of course. They knock Mei-Shun and Shin down with such lovely round shapes — that’s why they named him Mammal-kun. Not only for his species, mal means “round” in Japanese written 丸 or 円. Other examples include banana, coffee and papaya as well. Sorry to exclude you, star fruit, while we love your unique looks.
