Green

Several villages are being invaded by a flock (more like a cult) of hawks, led by none other than Gren, the malicious leader behind it all. By the way, he is green. The hawks put people under some spell where they chant "green" in an extremely annoying manner. And also did whatever Gren said. It's up to half-siblings Pond and Bob and military general Shrub (and the rest of the mission, but mainly these three) to stop them and retrieve the kidnapped (?) townspeople.
