I'd call this show "fluffy cute", because of it's lighthearted content, but at the same time hilarious. I had trouble telling some of the characters apart in the beginning, so I recommend watching a first two episodes carefully during the introduction of the characters (there are more than couple dozens and most of them are introduced in the first two episodes). Or you could doing some pre-flight research on Wiki, just search for "Pani Poni". There are a total of 26 episodes, and the ones I found are all English-dubbed. I'd like to watch the Japanese dialog with sub to get the full effect. Towards the end of the series, there are some racy images, but nothing too extreme. A lot of the scenes has multiple elements going on all at the same time, a little too chaotic, so you may need to rewind quite a bit to catch everything. The show is addictive; I watch all 26 episodes in two days (outside of Hulu).
