They are looking for them and Dorapin appeared
Dorapin: Hey. Are you Ace and Rev?
Ace: We are.
Ref: And hey! You're the one who's working with Dr Achimov.
Dorapin: Actually, I was a spy to him.
Ace: You are?
Dorapin: Of course. I'm a friend to Doraemon. The names Dorapin. Tell me, is Doraemon and Dorami is still safe?
Rev: No. They ran off to find their friends.
Dorapin: Oh No!
Ace: What wrong?
Dorapin: Dr Achimov is looking for them. And he's Robots are finding their Location. And he's obsessed to find the Bestfriend Telecard from them, and his mind is in a dark place. When I find out what's he's planning. He's gonna use the Bestfriend Telecard and Destroy them.
Ace: What? That's not good, Doc.
Dorapin: Don't worry, we'll find them. Dr Achimov said that he's found the "Robot Academy"- that is where the Robot's used to learn and graduate. Dorami and the others are in danger. We have to find a location to the school and warned everybody, because Dr Achimov is gonna eliminate them.
They saw Doraemon at his hiding spot
Ace: Doraemon, Dorami and the others are in trouble!
Dorapin: Where did she go?
Doraemon: I don't know. She... Left me and gave me this map, and I can't figured out where the school is... Wait... I remember what she said "When you have this map you hold the city in your hand." (Gasp) That's it! It's right there. There's us at the Street and the Robot Academy is over there!
Dorapin: Great job, Doraemon!
Rev: Yeah. Doraemon! Let's go!
Doraemon: Okay. I'm going to see them.
They went off to the Robot Academy and they made it here and they found their friends
Doraemon: Guys!
All: Doraemon!
They hug each other
Jaidora: You finally know where we are.
Pawaemon: Great job.
Dorami: So what are doing here?
Doraemon: Dorapin and I came here to learn you Dr Achimov is on his way.
Dorapin: We have to leave before they does.
Then the Dream Eaters appeared
Dr Achimov: Good job, Dorapin. Thankfully, you are very bit as predictable as I had hoped.
Dorapin: (Growl)
Dr Achimov: And this time Doraemon. I always knew you have the Best Friend Telecard with you and your friends. Now the Best Friends Telecard is mine.
He Captured them
Dr Achimov: Doraemon will never saved you.
Ace: Achimov! I can't let you have them!
Then Something just knocked him and Rev down
Hours Later
They wake up and the Robot Academy is empty
Rev: Where did everybody go?
Ace: Wait! Oh no! Dr Achimov is gonna eliminate Doraemons Friends!
Rev: We have to stop him!
They went off and they found Dora and his Friends tied up from Dr Achimov
Ace: Guys!
Then Doraemon, Noby, Sneech, Big G, Sneech and Dorami saved them
Rev: Way a go, you guys!
Ace: You did it!
They went off to somewhere and Dr Achimov is going after them. Then a Giant Dream Eater appeared, they are fighting it and they defeated it
Meanwhile,
Doraemon is at the Rooftop with his Friends
Dr Achimov: I knew you're not tough enough to save you're Friends. Just like Noby that make him begging so much.
Doraemon: I don't care that I'm not tough enough to save them. But I'm not letting you hurt them.
Dr Achimov: If you are.... Then how are about this!
Doraemon has fell off the roof and Dr Achimov fell off too, luckily he use his Jetpack, Noby is pulling Doraemon up
Nobody: Doraemon! Don't worry, I got you!
Then Dr Achimoff is gonna finish them off
Dr Achimov: After I'm through with you all, I will rule the world with the Telecard!

Doraemon: I know. I can't stay here from Dr Achimov for this. But it's wasn't the future that holding me back. But my heart is happy now. I'm ready to see my best friends again.
He Left
Ace and Rev look at the City
Ace: All that time, Doraemon let himself be hidden inside the nightmares that Dr Achimov gave him.
They are gonna leave

Rev: You again? Who are you?
They saw Mandarin as a Formless
