Trivia

 * If Nightshade is low on health, her tank treads will fall apart leaving her rolling on the ground.
 * If you beat Neon Nightmare using her, then you are automatically sent to Eternal Acres, possibly due to the fact that it wouldn't make sense to have Nightshade go against herself in battle. However, you still have to fight Goliath and Big Daddy, even though all three are part of Daddyland Security.
 * Nightshade is the only boss and unlockable character that is female. She's also the only female character to work for Daddyland Security.
