Summary: They will strike fear into the hearts of many.

When a hush fell over the castle after hours of the other residents being their usual selves, Nightmare knew there was trouble. And, like always, it fell upon him to make sure they weren't doing anything extensively foolish.

Heaving a deep sigh, the negativity-laden skeleton pried himself away from his desk/paperwork and set out to search for his rambunctious followers. Thankfully, the area he needed to check got narrowed down significantly once he became in earshot of their stifled laughter. Nightmare followed the sound until he eventually reached Cross' bedroom.

The monochrome warrior typically attempted to stay out of his fellow teammates' shenanigans. Being new to the group, he was still quite shy and uncertain when it came to his place in the gang and social interactions.

If events like these helped the abandoned Sans grow more comfortable in his new home, Nightmare supposed he could deal with it.

Hopefully, with minimal headaches.

The dark lord sighed and knocked on the door. Any noise happening beyond vanished, leaving an eerie silence.

"Cross, may I come in?" He asked, putting on his best "I'm not mad, just tired" face.

The door was slow to open, and when it finally did, it was only cracked enough for Cross to peek out of his room.

The swordsman nervously glanced away from him, gripping the door. "Good morning, Nightmare. I... Uh..."

The Guardian of Negativity resisted the urge to sigh. Despite his best efforts, it appeared the newest member of his team still remained extremely wary of his presence.

"You need not worry, Cross. You aren't in trouble. I merely require to check on the three that might be." Nightmare amended.

Cross stared at him, searching for something, before hesitantly shuffling to the side and fully opening the door.

"Betrayal!" Killer dramatically gasped while Horror and Dust pouted.

The trio were seated on the floor alongside four small fuzzy, noodle-like creatures with beady little eyes; Each animal seemed to be adorned by a tiny replica of one of their outfits. They were no doubt Error's handy work.

He would need to apologize to the glitch later.

The negativity-laden skeleton walked in and pinched the bridge of his nasal cavity, gesturing at the scene with his free hand. "What is this supposed to be?"

"Your new gang!" Killer chimed, regaining his excitement. The hoodie-clad murderer promptly grabbed his tiny doppelgänger to show it off.

A light frown marred Nightmare's gooey skull. "Return them to the forest at once. Weasels are not indoor creatures, and I won't have them ruining the castle's expensive furniture."

"But they like it here!" Dust whined as the weasel in his hands hissed, trying to wiggle free while nibbling at his phalanges.

The dark lord leveled the other with an unamused expression.

"Clearly, you both have different opinions on that matter. Put them back wherever you got them before lunchtime." He continued with a tone of finality, "And make a reminder on your calendars for your new rabies shot appointments."

Killer, Dust, and Horror whined in complaint while Cross gave a silent nod.

"You wouldn't need it if you didn't insist upon playing with the wildlife." Nightmare chided. "Perhaps this event will be enough of a lesson to keep you from bringing wild animals out of the woods."

It wasn't. Evident by the fact Nightmare found several deer grazing on the books in his office the very next day.
