Trivia

 * First appearance of the Squirrelanoids.
 * This Episode aired out of order.
 * This is the first time we see Mikey's room.
 * The episode is a very strong homage to Ridley Scott's popular sci-fi/horror film, Aliens, with the Squirrelanoids' appearance and behavior mimicking the film's titular antagonists, as well as specific lines and scenes being lifted directed from the film as well.
 * Michelangelo names the Squirrelanoids after the Alienoids that appear in his comic, "Invasion of the Alienoids" (which also echoes the episode's title). The comic itself appears to be a much closer retelling of the film Alien.
 * The title bears heavy resemblance to the 1987 series episode, "Invasion of the Krangazoids" and the 2003 Fast Forward episode, "Invasion of the Bodyjacker".
 * In Mikey's room, he has a cardboard cutout of Chris Bradford in his human form.
 * Written on Michelangelo's surfboard is the name "Cipes", obviously after his voice actor, professional surfer Greg Cipes.
 * Mikey also makes the quote "Game over, man, game OVER!", a line from the Alien sequel Aliens.
