Trash Alien's Planet is an unnamed planet that had been colonized by Trash Alien for use as a secret hideout. He built a massive door that would open for his ship and close behind him into the planet's crust. Blasternaut pursued him here in order to rescue Spot, who Trash Alien has held captive there. When Blasternaut arrives at the planet, Trash Monster has Spot bound and gagged in his ship. It is unknown what became of the planet afterwards. ("Math Blaster Episode 1: In Search of Spot")
