That whale-looking thing is not a living creature, it is a representative of Pluto’s ‘heart’/'whale’ and 'donut’ shape on the planet’s surface. (Once we get a clearer view, I wonder what they’ll name these formations officially..)
I just can’t stop fangirling. I really like to to thank Himaruya Hidekaz-san for creating Hetalia,
for making this world more beautiful! And thank you, too, to the artist rosel-d (cioccolatodorima) for sharing his lovely Himaruya-style Hetalia artworks. Both of them are truly amazing. Arigatou! I LOVE HETALIA!
