Mabel and Dipper had woken up to find themselves in the middle of what appeared to be a forest. The mystery twins decided to look around and figure out how they even got here and where they were.

(Mabel) W-Where are we Dipper?!

(Dipper) I... I don't know.

After a while of walking around The twins came across a town. They were shocked to find that everyone in the town was in anthropomorphic animal. But they were really shocked after coming across a mirror and what they found their appearance to be. They were no longer human, instead of they were both small brown hedgehogs!

After a bit of chest standing around shocked Mabel picked up her pig, Waddles and they continued on. The two of them were alone in this new world, so the most they could do right now was stick together. Then out of nowhere, The twins were grabbed and pulled into a random alleyway. Mabel had dropped Waddles and her pig had run off to hide.

(???) Well, well, well. Looks like I've got my self a couple of wondering children. What's the matter kids can't find your parents? Hahahaha!

(Dipper) Who are you?!

The green hedgehog introduced himself as a Scourge the hedgehog and told the twins that they were going to be coming with him as he got ready to throw a warp ring. Luckily for them Dipper was able to act fast and flipped over and polled on scourges arm resulting it to dislocate from his shoulder.

This caused Scourge so much pain that he dropped the twins and they ran as Mabel quickly picked up her pig. Unfortunately for them Scourge was able to relocate his arm and he immediately started chasing after them. The twins called out for help but soon found themselves being cornered in another alleyway! But then out of nowhere two figures had dropped down right in front of them.

One of them was a black hedgehog with red stripes, rocket shoes, and gold rings on his wrists and ankles. The other was a white bat wearing a black and pink jumpsuit, White and pink boots and A pair of gloves that were also white and pink. The twins didn't know who they were but... for some reason... they felt they could trust them.

(Scourge) Well if it isn't Shadow and Rouge. What do you want this time stripes?

(Shadow) Let the kids go, Scourge!

(Scourge) Hahaha. Not gonna happen stripes.

The three of them then engaged in battle as the twins sat in the background watching. Mabel hugged her pig Waddles with fear while her twin brother had pulled out one of the three journals that their great uncle Ford had given him. He hadn't used them yet so all three were empty. Remembering their names were mentioned he wrote down each of their names first, starting with Shadow. He drew a picture of Shadow on the first page of journal one.

He couldn't get a whole lot of information other than that he seems very powerful. So until he could get more information he decided to move onto the second page which had rouge his name on it along with a picture of her. The only information that he could put down so far on her was that she appeared to be a fruit that and that she was an incredible fighter.

After the fight was over they handcuffed Scourge and Rouge made a call to someone that she knew in an alternate dimension. Two minutes later Zonic, Zespio and Zector came through a warp ring and Took discourage with them to know zone prison thanking the two G.U.N agents as they left. As soon as the no zone cops and Scourge were gone, the two agents went over to check on the twins.

The twins were a little scared and confused. They didn't know who these two were, then again they did just save them. Shadow and Rouge note down to the twins level so that way they wouldn't intimidate or scare them. Rouge was about to ask them if they were okay but Shadow beat her to it. Rouge wasn't too surprised however considering Shadow was going to be a father soon anyway.

After a while Shadow and Rouge and Chomppy Club the twins with them to G.U.N HQ. The twins didn't know what was to come, but one thing is for certain... this was only the beginning of a brand new adventure.
