"WE'RE IN THE WALLS. THE WALLS! THE WALLS!" Lynn shout-sang obnoxiously. "I can make a song about anything!"

"Please don't," Cody replied immediately.

"Nah," Lynn shouted, and then continued to ramble nonsense. Meanwhile, Cody was debating whether his sister lied or not. The only way Cate had gotten into his Universe and back was through a time malfunction. Could there be a systemized path from one universe to another? Was that even possible? A wave of cool air pulled Cody out of his thoughts.

"Oh, I think this is where I went before!" Lynn smiled and bolted down the pathway. Cody sighed and ran after her. Soon, they reached an opening, a door, and Lynn immediately pulled it open without any regards to their safety. It was Snowdin, but wrong.

Shops were empty, dust lay scattered about, and it was completely quiet.  Feeling watched, Cosy mumbled "Lynn, I think we should-"

"Explore?" Lynn cut him off and then ran towards the end of Snowdin. Yet again chasing after his sister, Cody followed. Eventually, they both heard Papyrus's voice. Cody halted out of reflex and Lynn kept running up, to see Frisk facing Papyrus, who had barely any health. She was just in time to see Frisk wave the knife at him, knock his head off, and step on it. Her eyes widened as Frisk turned around. "Uh, Cods?"

Before she could finish the last words, Cody had her by the back of the sweater and was off. Lynn was indifferently being waved about behind him, and before long, they were back in the walls.

"I...have no idea how these things are even possible," Cody muttered. "They are an anomaly to science."

"That was scary."

"Yes it was. It seemed like a geno-"

"Let's go again."

"No!"

"You ruin all the fun," By the time this conversation was over, they were back in their house.
