If you're after a light and short series to while away 50 odd minutes of your time then this is certainly worth it. The characters are nicely written and designed, meeting a certain level of Shoujo fanservice whilst remaining fun and interesting enough for 13 short episodes. The world of anthropomorphic sea creatures that it builds up is charming and engages with the imagination and yet intentionally traps itself within the mundane confines of a bathroom. Whilst all the aesthetic aspects of this show are pretty average, the characters and the humor are charming and effective enough to keep the viewer engages and enthralled.
