Dual Prologue.

In two little towns, two kids were called.

- Dipper/Steven, i must tell you something - said Garnet/Stanford.

- What is it? - asked the kids.

- You see, i found giant anomalies in a place in the other side of the world, we/you and Mabel are going to investigate.

- How is that place called? -asked the boys.

- Gravity Falls/Beach City - said Garnet and Stanford in a serious tone.

One Week later.

Steven Universe was in the Warp Pad alongside the Crystal Gems: Garnet, Amethyst and Pearl. Meanwhile, Dipper and Mabel Pines were in the Airport with their two Grunkles, Soos and Wendy.

- Stanford, are you sure thay they can take care of themselves alone in an unknown place with anomalies? - asked furious Stanley.

- Don't worry Stanley, this is more of a recognition mission, they are just teens so they shouldn't raise suspicion.

- If you say... - groaned Stanley.

- Crystal Lantern? - asked Ford.

- Check - said Dipper holding the lantern which can change the size of the things.

- Journals 1, 2 and 3? - asked Ford again.

- Check - said again Dipper.

- Grappling Hook? - asked Ford one last time.

- Check! - answered Mabel raising her beloved hook.

- Very well, with these three things, especially the journals with their knowledge and spells, you should be fine - assured Ford.

- Remember to bring valuables things, like gems and such - said Stanley.

- Are you sure that you don't need a bat in case that you find a Pinata? - asked Soos.

- Yes Soos, we are sure - answered Dipper.

- Good luck- Wendy said simply.

- Goodbye! - said the twins waving while getting in the plane.

At the same time, the Crystal Gems started the Warp Pad.
