Traps, tricks and easter eggs can be found hidden around the house on every night. Some of the them require rooms that that have been unlocked on previous nights. Getting too close to a trap will generally result in a game over, tricks are harmless but are usually a hindrance and easter eggs are hidden and may reference things outside of Night Blights. Below is a list of known traps, tricks and easter eggs.
A Night Blight will sometimes hide in a present box. The Night Blight’s eyes will be seen through holes in the box meant for them to peer out through. Although it looks sweet and inviting, don't go too close. A Blight will be waiting inside for you.
A Night Blight will sometimes post arrow signs that say "Free Toys" and lead towards the obvious Night Blight wearing a jester cap and surrounded by Toys. Don't even think about getting close to those toys.
FREE TOY (Real)
In this trap, the Night Blights attempt to scare you by breaking down a door and lighting up bulbs that look like eyes. There is a Robo-Chris toy in the end of the room if you go inside and you will get the achievement 'Hero' if you pick it up. However, leave the room carefully as a Night Blight will be waiting in the shadows near a wall.
Sometimes, the teddy bear in your bedroom will look just like a Night Blight. DO NOT TOUCH IT. Touching the teddy bear Night Blight will cause an instant GAME OVER.
UNDER THE CRIB
Sometimes a Night Blight will hide under the baby brother's crib, forcing you to use a stool or an alternate path to spin the mobile.
LOCKED IN THE BATHROOM
Sometimes, the Night Blights will briefly lock you in the Bathroom and start snickering and turning the lights on and off constantly before opening it again. While it is harmless, it does wastes your time, allowing Blights to escape.
LOCKED IN THE CAR
Sometimes, the car in the garage will open and you'll be able to get the Blue Owlby inside. However, once inside the Blights will briefly lock you in the car before opening it again. This will not kill you, but it wastes time, allowing Night Blights to escape.
Night Blights will often close the bottom drawer of the toolbox in the Garage after you press the button, which forces you to use a Red Stool to get up to push the button.
Claw marks will randomly appear throughout the night on Wardrobes, walls and bookshelves. They serve no purpose other then giving the player a little scare.
The Night Blights will sometimes turn off the lights for a bit, plunging you into darkness and making it harder to see.
Sometimes when going through any doorway a cardboard cut-out of a Night Blight will pop up, along with the jumpscare scream. It's harmless, but scary.
Sometimes in the bedrooms, it looks like a large Night Blight is waiting for you, but it's just a cardboard cutout. When the Blights realize it doesn't fool you they'll remove it.
FAKE BLIGHT 2
Sometimes by stairs there will appear to be a Night Blight waiting for you. A closer look reveals that it's actually just a crude drawing.
Your Teddy Bear may move around during the night. Teddy is known to sit on top of the Wardrobe in the Player's room, disappear on his own, and sometimes stand behind the player with a menacing smile. Whether or not the Nights Blights are messing with you or Teddy moves on his own is still unknown.
Sometimes a Night Blight will call with a backwards message that says, "Are my children bothering you? Hahahaha..."
A Night Blight will sometimes sing in the shower.
WRITING ON THE WALLS
The Night Blights will sometimes write messages on the walls in red marker or crayon. Known messages are HUNGRY HUNRGY HUNRGY, GO BACK TO SLEEP and YOU SHALL DIE.
Randomly, a light blue and blue beach ball will roll down the stairs.
Sometimes the Blights spell messages such as NO and HATE on the fridge.
On the coffee table there is a statue of a green dragon that seems to be made out of crystal. It is a reference to the Crystal Statues, one of the main collectables in Spyro the Dragon.
In the basement, there is an arcade game about shooting giant Night Blights in space. It is a reference to the arcade game Space Invaders.
