I'll review the series as a whole and not just the OVA's. I didn't see much of a difference in quality anyway.

The plot's simple and not that important. The events in each episode are maybe a little cliché but they're so well bended to fit the characters of this anime.

The dialogue is hilarious and sometimes really absurd because of the diversity in characters: there's a monkey, a shark, a giant squid, even the terminator, ... I didn't like all characters as much but most of them are a great addition to the cast.

The animation is good as well, switching style and background at just the right moment. One minor remark is the blood wich is strangely rainbow colored. It makes it more noticeable but I had to think twice before I realized it was blood.

I wanted to watch this for a while now but I decided to watch it with a friend and it was worth sharing the experience. Almost each episode was pure gold. (show less)
