Nightmare House 2 Uboa

Nightmare House 2 Uboa

A video of Uboa in Nightmare House 2.

Uboa comes from a 2005 adventure game named Yume Nikki. In one particular area of the game, before murdering a girl named Poniko, there is a remote chance that after turning off the lights in a room, Uboa will appear. Uboa is mostly known for his disturbing, contorted face and the heart-pounding music accompanying Uboa's appearance. This character holds a nightmarish grasp on many players' hearts due to Uboa's sudden and unpredictable appearance. Many who discovered him by pure accident were scared out of their minds. Uboa serves as an easter egg in Nightmare House 2 in Chapter 4 while confronting the Shadows.

During Chapter 4, the Patient finds himself in a hallway where several Shadows will appear. At the end of this hall, the Patient may stumble upon an empty room with a button that seems to do nothing. If the Patient repeatedly presses said button, Uboa will eventually appear in the center of the room with an unnerving music track playing in the background. If the Patient gets too close to Uboa, he will be teleported outside of the room, and the door will be locked.


NightMare House 2 WTF??? Luigi?

NightMare House 2 WTF??? Luigi?

A video of Weegee in Nightmare House 2.

Weegee is the odd version of Luigi. He has a brother named Malleo who is the odd version of Luigi's brother, Mario. Weegee has the ability to hypnotize people when he makes eye contact with them and eventually starts a Weegee virus. This virus makes other individuals have the same exact face as Weegee. Weegee is best known for his creepy stare and is arguably one of the most creepiest characters of the Mario series, despite being a meme and not an actual character licensed by Nintendo. Weegee serves as an easter egg in Nightmare House 2 in Chapter 2 in the radiology department.

While in Chapter 2 of the game, the Patient finds himself wandering around the radiology department. If he goes into the first door on his left, he will find a room with a recycling bin in the corner. If the Patient moves the recycling bin aside, he will find Weegee in the corner gazing at him continuously.

"Look at my horse, my horse is amazing.

Give it a lick! Mmm it tastes just like raisins.

Of a stroke of its mane, it turns into a plane,

And then he turns back again when you tug on his winky. Ew, that's dirty!

Do you think so? Well, I better not show you where the lemonade is made.

Sweet lemonade, mmm sweet lemonade, sweet lemonade, yeah sweet lemonade..."

(zombie plays piano)

"Get on my horse! I'll take you 'round the universe and all the other places, too.

I think you'll find that the universe pretty much covers everything!

Shut up, woman, get on my horse."
