Frogs in Fiction #23 - Sgt. Frog

Known as Keroro Gunso in Japan and originally published as a manga (1999 - present) this is the humorous, pop culture laden story of a group of five frog-like aliens (the Keroro Platoon) who try to take over the Earth but are constantly side-tracked by meaningless distractions. It's still pretty popular and has had numerous adaptations, including a 358 episode anime, and several movies and video games. (Obviously though, it's not the most realistic story around. I mean a sergeant leading a platoon... consisting of five... Clearly they were not aiming for accuracy)
