Summer Days with COO

Watched 'Summer Days with COO' on Saturday. Its a Japanese anime and its vry touching. I cried in the end...
its a story abt a kappa(河童) and a boy, Koichi. Koichi found a fossil by chance "resurrected" it and named it COO. from thr, their friendship developed and things happened...although COO left in the end, he promised they will meet again.

its one of the best anime i hv watched. think they got quite a few awards too!
