Sonic and friends let the monsters into their base. After a few hours Tails had a hunch on how they had got there.

"Everyone sit down I think I have a way on how to get you guys back home!" Tails said and everyone sat on the couch. Tails opened up a presentation

"As you see this is footage of green hills at the exact same time you arrived." Tails said and the footage played then Tails paused it at the exact same moment the portal was about to close. Something had spread out across the land and Cas recognized it.

"Those are chaos emeralds! But how can there be 7? I have the 7th o-" Cas stopped talking when she realized her chaos emerald was gone

"WHAT?! BUT I CAN STILL USE MY POWERS! HOW CAN USE THEM WITHOUT MY EMERALD?!" Cas said in shock

"I had actually figured something like that was going to happen. Your powers had become a part of you so the chaos emerald left and went somewhere else." Tails explained

"No wonder Eggman had 7 chaos emeralds!" Sonic said

"Yes well any way in my theory when we destroyed eggmans chaos robot Chaos control happened but not in our dimension. It instead went to your dimension and took only you guys which explains why we only have you guys." Tails explained

"So what you're saying is I don't have my employees here? How am I going to sell my MTT brand without employees?" Metaton said sadly

"Well how can we get home?" Toriel asked

"If we can get all 7 chaos emeralds… we can use chaos control and send you guys home!" Tails said

"Yes! A treasure hunt for the GREEEAT PAPYRUS! I love this idea!" Papyrus said in joy

"Eh if it helps us get home I'm all for it." Sans said. Suddenly they heard laughter outside. Cas sighed

"Can't we get A BREAK?!" Cas said in anger and ran outside and everyone followed. They all saw a ton of badniks. Behind all of those robots was a giant Death egg robot with eggman inside

'MUAH HA HA HA HA-" Eggman was cut off by Cas

"Get on with it! We're trying to figure out how to get these guys home!" Cas said in anger. Eggman noticed the newbies and scanned them. He had picked up a large power source coming from Frisk's determination. He aimed a net blaster at the girl and shot it. Sans teleported, grabbed Frisk and teleported away

"JUST HAND OVER THE GIRL!" Eggman yelled

"I will not hand over my child!" Toriel said

"If you want the kid you're gonna have to go through us!" Undine yelled with a spear in each hand

"I'll come back later for her, but when I come back you better hand her over!" Eggman said and his army left

"Fighting that dude is that easy? You should always have a break fighting that guy!" Undine said

"No he never leaves like that. He always fights until we destroy all of his robots!" Knuckles says

"We'll deal with it tomorow for now let's head inside it's getting late. We can show you guys some guest rooms we have." Amy said
