Trivia

 * Mucilator is the first form of the Nemetrix to be used for hunting the right prey (Crabdozer, Buglizard and Slamworm were all used for aliens that aren't the species they prey on). This was because it saw what alien Ben was before it transformed.
 * Mucilator is wrongly spelled "Mucillator" in the Omniverse video game.
 * Mucilator's name comes from the word "mucilage" which refers to sticky substances similar to gum or glue that can be used as an adhesive. This is refers to the sticky sacs on its body that it uses to trap its quarry, notably Crashopper.
