For unknown reasons, he kidnapped Spot, taking him to his secret planet. In the official art for the first game, Trash Alien simply has Spot in his arms, but in the actual game, Spot is chained up in the ship and gagged with a piece of grey cloth. Blasternaut secretly persued and snuck into the planet, soon defeating Trash Alien and saving Spot. ("Math Blaster Episode 1: In Search of Spot")
Trash Alien was then locked up in planet Lockemup along with many other space criminals. ("Mega Math Blaster")
