Luna gets worried sick about Yuna/Searching all over the worlds

Here is how Princess Luna gets worried sick about Princess Yuna in Fantasyland Rescue.

Meanwhile at the following morning in Equestria, Princess Luna was worried sick about Yuna if she's okay or not.

Princess Luna: (in a loud voice) Yuna! Dipper! Mabel! Lightning! Mater! Cruz! Dusty! Where are you!?

Harumi: Where are you?

At Disneyland aka the World of Disney, the search party kept on searching near and far. At Zootopia, Flurry Heart couldn't find them anywhere, not even the ZPD.

Princess Flurry Heart: Chief Bogo, did the ZPD find Yuna, Dipper, Mabel, Lightning, Mater, Cruz, or Dusty yet?

Chief Bogo: Not yet. But, we'll find them. Don't you worry, Princess Flurry Heart.

Clawhauser: Sorry, Sir, still not traces of them.

Chief Bogo: We'll have to keep looking, Clawhauser, we may got no choice.

At the Golden Oak Library, not even Fizzlepop, Grubber, or anyone, anypony, or any creature else could find them.

Ford Pines: Any sign of them, Gyro?

Gyro Gearloose: (through his binoculars) No sign of them.

Grubber: Hey, Guys, I think it might be them! Yuna! Dipper! Mabel! Lightning! Mater! Cruz! Dusty! Is that you guys!?

Then, Opalescence meows in fear and runs off through the bushes.

Grubber: Opal, would ya get out of here!? We're working on our own search and rescue!

Fizzlepop Berrytwist: (sighs) I hope they're okay.

Ooblar: Yeah, me too.
