Godzilla Island was a Japanese tv series about Godzilla and other monsters battling invaders from Planet X that ran from 1997-1998. What makes this show so interesting is how each episode was only three minutes long and that most of the monster scenes used toys being moved around. Okay, technically they were figures made from the molds of various Godzilla-related toys, but I think you get the point. From what I understand, the show was apparently intended for children to watch before heading off to school (and to advertise Bandai Godzilla figures).
