Well I haven't see so many inflatable animals in a anime/manga and I think the Japanese can make more episodes with that
things like episode 11 from Sister Princess because anime/manga girls can sit on it and have fun in the water :) I think
great inflatable animals are a inflatable shark, a inflatable whale, an inflatable dolphin and a inflatable turtle
because this four animals are all so cute like this two images:
I like the two images so much and I hope the Japanese make a new episode in the future with cute girls like the girls from Stratos4, Chobits, Da Capo, Galaxy Angel, DearS, Girls Bravo and so on :D What did you think about it?
