Both of them were so interesting. Oktapodi was adorable to me. At the end, when a sea gull caught the orange octopus, pink one shot her?self to the target.After that, they all would fall into the sea. Those two get together again. But a fisherman would catch them and put them in a water tank. Then, they do the same routine like in the film, I guess.
Mermaid was a bit difficult for me. I just couldn't understand how people in that country knew he was daydreaming. He wouldn't tell anybody about his fantasy because he was one of the people and must have known the rule there... Anyway, I guess the theme of Mermaid is freedom of ideas. Also, Osamu Tezuka, as a cartoonist, maybe wanted to tell us how precious our imaginations are.
