Blue Astronaut's Home World

The home planet of the Blue Astronaut is a small, forest covered land with a giant tower in the middle that the Constructor was on top of. After recovering his Spessship, the Blue Astronaut returned him, only to meet the only other citizen of the planet, the Red Astronaut who begs him to save "us"

Trivia

 * Strangely, the Spessship, the Red Astronaut, and all the trees are gone after you defeat the constructor.
