(Just pretend that Frisk is a skeleton in the picture)
As they walked into the core, they had their eyes and ears open for any danger around them, Aphlys was still on the look out for any monsters near them. When the continued walking, music was still heard from the resort from far away as well of wind blowing through the Core, giving them the chills. They reached to a sliver elevator, Undynes walkie turns on, "Guys you made to the core, well almost, just go to the elevator and go to the top of the Core." Said Alphys. As she waited for them, they walked to the elevator and pushing the button to go up........ nothing happened. Undyne called Alphys, "Yes?" "Hey Alph, the elevator isn't working," he said. "What? The elevator should be working... w...well then go to the left side of the elevator, there is a entrance there," Alphys said. "Alright thanks."
"Lets go to the left side entrance," she said as she walked towards it. The skeletons followed her to the entrance and once they got to the other side of it, it was pretty wide and little dark around the corners. Then the walkie turns on again, "Okay, you should be able to make it through here to get to the Core," said Alphys. Then footsteps were heard near them, "Watch out guys something is coming towards you!" She quietly said as she stopped talking to them. It was Madjick coming towards them looking like they were ready to attack, they quickly hid Frisk behind them and did small battles with it, after a while they spared them and it walked, well rather flew away. They sigh in relief as they were told by Alphys to just keep heading forward. As they continued walking to the other side of the open area they were at, they were stopped by a electric path way looking like a puzzle, Alphys helped them by making the electricity go away for a few seconds but they had to be fast. While traveling a little more more monsters came by and started to attack, it was strange. Then after that they came open lasers, it was pretty difficult to get through especially for Papyrus since he was pretty tall but not as tall as Undyne because she was strong. After going through all of that, they noticed that some of the monsters that are in the Core, attacked them, but they just spared them, one of them accidentally hit a special attack at Frisk making her HP go down, it caused the three of them get really pissed and that made them scared and ran away. As they nearly made it to the end of the Core, more puzzles were made to be a completed to continue, Paps was enjoying it but the others got bored. After completing them they heard footsteps coming towards them again, but this time, Alphys didn't called them. Before the skeletons teleported to hide, guards and other monsters were already in front of them. They had to stand in front of Frisk in order to hide her from them, that was then when one of the guards started to speak, "Undyne, the king and queen asks of you and your two other friends to come to the palace immediately," they said, this caused the three of them to stay quiet, Undyne broke the silence, "Alright then, we'll go once we are done searching around here." She said, they nodded as they went waiting for them in the next room. That was then when they were gone Undyne sighed heavily, "Guys we have to leave Frisk here," she said. "B...But why?!" Asked Papyrus, "If we are going to the palace, they can't see Frisk, we can't  hide her. If you teleport her somewhere where nobody will be looking at sans, I'm sure that Asgore will have all of the guards in the area and outside," she said, both boys were upset and worried. Frisk looks at them with a upset expression but they didn't see her, she then turned to see Gaster who was behind her, Gaster looked at her with the same expression as her but then he nodded to agree with what Undyne said. She then looked back at them, "Guys.... Undyne is right, I can't be caught yet, I need to show my self, but with all of these guards around they'll think I'm a stranger and maybe they will take me away, and I'm sure that Asgore and Toriel will not agree with you of me is... me. I'll stay here being hidden or try to be as possible as I can, once you guys are back I'll be in front of the door to The palace," she said. They looked at her then back at them, they agreed and but they told told her to just follow them behind them and once they get to the door, she stop there and wait. As they stopped talking they started to walk with the guards with Frisk behind them, until they made it to a elevator door. Once they made it, they quickly hugged her before leaving her behind, when she last hugged sans, he said "Kid..... take this," he summoned a special attack bone and handed it to her, "Use it to protect your self.... take care of your self and be safe.... promise me that?" He said "I will sans," she said as he let go of her. "See ya on a bit," he said "Alright," she responded as the door was closed, she sat down on the floor waiting patiently for them.
