The short film is about a boy who lives and works on a farm. One day when going to sell vegetables at a market, his cart breaks down. Two strangers, a frog and a mole, offer him a strange seed in exchange for the vegetables. The boy accepts and finds that the seed grows into a miniature planet. It continues growing as he tends to it, forming an atmosphere, weather systems and life. After being taken back to the city, he meets the stranger who sold the seed to him, and they release the planet into a galaxy of similar planets, where it will grow for years until becoming a real planet.
As alien invaders plot to conquer the Earth, two Boy Scouts steal a mini-submarine and discover Gamera in their midst. Transported to the alien's spaceship, the Scouts are menaced by the evil inhabitants, including Viras, a squid-like monster that grows to colossal size to battle Gamera.
The peaceful planet of Jillucia has been nearly wiped out by the Gavanas, whose leader takes orders from his mother rather than the Emperor. King Kaiba sends out eight Liabe holy seeds, each to be received by a chosen one to defend the Gavanas. Each recipient, ranging from hardened General Garuda to Gavana Prince Hans to young Terrans Meia, Kido, and Aaron all have different reactions to being chosen.
