A boy finds a strange (initially fossilised) creature, a Kappa named Coo, with a kind character. The family gets attached to Coo and struggles to keep him secret from the public. Coo soon starts to feel lonely and separated and wonders about his own kind.
Even though there's a lot happening in between and afterwards, the movie has a very, VERY calm and smooth way of storytelling but doesn't create a feeling boredom. If you're looking for action and a propulsive plot, then this is nothing for you.
Most characters have depth and happen to be very open with their feelings - this, the sorrows of Coo and what they entail make "Kappa no Coo to Natsuyasumi" an exceptionally empathetic and touching anime.
There are moments of fun, happiness and sadness, even some of shock. Everyone who usually cries a little (or more) in movies will definitely cry while watching this one.
On the side panel you can see that someone set the genre to "Adventure" .... I don't think that fits too much. Slice of Life, Drama and (a little) Comedy are way more fitting.
The visual art in "Kappa no Coo..." won't impress you all too much - pretty solid and modest are the words coming to my mind. All in all more than enough to catch the atmosphere and the viewer.
If you're liking emotional motion pictures with strong characters and strong plot then you shouldn't miss this one.
